Hello guys/girls,

I just purchased a 2005 CRD. I traveled to Dallas to pick it up from Florida and Just got back. I am very happy with the power and the handling.

But of course I would love to make it more powerful. I am sure there are a few tricks to squeeze some power out of these things besides the aftermarket products. Anyone want to lend me some info? I know how to use the research button but if I can get a list to start with I would be really happy and grateful.

I am coming over from the Cherokee SRT8 site where I was one of the pioneers and main contributor to performance upgrades for it. I have a site with detailed instructions (w/pics) on how to do several mods and have the ability to contribute the same way here. I hope you guys are as open and friendly as the SRT8 gang. Thanks for your time.... CHRIS

P.S. (shot in the dark) Has anyone seen this one or know any history on it.... i.e. Previous owner and Mods reason for selling it? It has a infinity sub, amp under the passenger seat and a JVC DVD head unit.

BTW..

It seems to smoke a bit under light - moderate accel and ofcourse under hard accel. Is this normal.
And I the three tanks averaged our 17 (first) 18.5(second) and just over 20 for the third. Oddly i was driving faster on the last tank 70-85 consistently. Seems low to me.

My intended MOD list... IF i am misguided with these let me know!
Edge Trail jmr
K&N filter
2 1/5 straight pipe... from cat back removing the downsized pipe from the cat.
2" lift
Rubicon or factory gray rims

ARB front bumper?

Welcome Fast
There is a wealth of info here.

You should check out this website as a first priority.
http://www.greendieselengineering.com

Many here have gotten this tune, me included. I average close to 30 mpg with winter fuel.

welcome

K&N is not nessary and you will get flamed for the mention of that here on a diesel. what many like here is the amsoil EEa air filter. I have one too.

Edge Trail jmr Go with GDE. Fixes more problems than a box; gives more performance than a box. Since GDE came around, I haven't heard a single person mention another chip/tune
K&N filter Amsoil Ea Filter; K&N is bad for this engine
2 1/5 straight pipe... from cat back removing the downsized pipe from the cat. 2.5" (not 2 1/5) straight pipe or muffler, removing the downsized portion.
2" lift
Rubicon or factory gray rims

ARB front bumper?

See my comments in your post. Just some helpful recommendations... you can search the site for more info on each product. Some might also recommend a CCV Filter (Provent or DIY)

Congrats! It's a sweet looking ride!

Clean the MAP sensor, it on the back of the intake manafold, that helpd mine smoke less. directions are in the tech section

Thanks for the replies.

I will look into the GDE site. Maybe give them a call next week.

I miss typed the exhaust size 2.5 is what I intended....oopps. Long two days!!! Flying out to Huston/Dallas driving back... etc!

what are the necessary noob mods when you first get a stocker?

No worries. I'm from FL as well, but I live in AZ now... I know that drive :5SHOTS:

Noob mods/first things to do:
Clean the Map sensor and CAC hoses (see CRD Tech page for how to) ~30-45 minutes/$0
Unplug the fuel heater and consider replacement filter head; check for potential leaks (see CRD Tech) ~5 minutes/$0
Amsoil Air Filter exchange ~5 minutes/$30
IMO, GDE is a "noob mod." The benefits are numerous (and they keep releasing updates!). Besides, I've gotten as much as 10mpg over EPA highway estimates thanks to the GDE tune!!! :pepper:

After that, you can start considering exhaust options, CCV filters, lifts, etc. etc. etc. Enjoy!

First things first, unplug the MAF sensor to disable the EGR and stop the flow of exhaust (read: soot) into the intake. Link here: viewtopic.php?f=98&t=22631 It will cause a Check Engine Light, but it is a good temporary fix until you can make a decision on a GDE tune, other tune, or SEGR, which affect EGR recirculation.

Next, install an Elephant Hose to stop oil mist flowing into your turbo and intake tract. Link here: viewtopic.php?f=98&t=22703 The stock setup allows oil mist to flow into your intake (pre-turbo). Combine that oil with soot from the exhaust, and you get sludge in the intake. It builds up, restricting the flow of air and affecting the MAP sensor reading, which is next.

Clean the MAP sensor with chlorine-free brake parts cleaner. Link here: viewtopic.php?f=98&t=22630 Make sure you do not lose the small washer on the bolt.

So now, you've spent 30 minutes, and little to no money, and you will have a much more responsive and economical machine. Get out on the Interstate and run it hard to clear the cat of any soot buildup, and to enjoy the power. Now it's money time. . .

Order a test kit from Blackstone or another oil analysis lab, drain the oil and catch a sample to send off to find out about any possible abnormal engine wear. Refill with a quality 5W-40 SYNTHETIC diesel-rated oil (such as Mobil 1 Turbodiesel Truck or Shell Rotella T) and replace the oil filter with a quality filter such as Wix or Purolator Pure One. (Unless you have solid records from the previous owner/ dealer that indicate this is not necessary) Replace the drain plug with a Fumoto valve, this will make oil changes infinitely easier and prevent you from damaging the threads on the cast aluminum oil pan. (Link hhere: http://lubricationspecialist.com/front/ ... 5&p=Fumoto Greg with Lubrication Specialist is a LOST member)

After these simple things, the world is your oyster. Keep surfing LOST, and you will find a wealth of information about the various options for the GDE tune, SEGR, Provent, exhaust mods, lifts, etc. Most members have their mods in their signature line, if you have a question, PM them and 99/100 times you will get a positive, informative response. After about a month or so of regular visits and reading, you will become familiar with common issues and fixes discussed here on the board.

Glad to hear the SRT forum is friendly and helpful. You will find this site very helpful and beneficial.
Having no gassers I never spend any time lurking and when I do it will be looking at other 4WD based sites and man can some of them FLAME!
You will not see that here- only good technical and constructive debate and downright excellent advice helpful towards your needs.
Even if you go where no one else with your modifications you are still happily part of the group.

Welcome to LOST!

welcome to LOST Fast.
Believe it or not but i think ive seen that crd on sale on ebay and with the Texa Imports image.

how many miles does she/he have?

FastSRT8GC · **Joined:** Mon Jan 04, 2010 9:52 pm **Posts:** 55

Once again Thanks to all!!

These are the answers I was looking for.
I took her to the dealer today. Looks like nothing was done.

The TQ converter was never changed, the PCM and TCM updates were never done.
So I have an appointment for monday. We will see what else they can find since it is still under warranty 53k.

It has a major oil leak on the drivers side up the side of the motor.
It has a good rear diff leak at the drive shaft.

How can I stop them from doing the TCM update?

Today it got tinted and 2.5 straight pipe

VMKJCRD · **Posted:** Fri Jan 08, 2010 6:50 pm

what ever you do, dont let them update your TCM to F37! My fiance got one for me with out the update and she paied 500 dollars for it :shock:

. If they say they have to go somewhere else or find someone in your area and ask if you can swap your TCM with them for the day.

Good luck

linewarbr · **Posted:** Fri Jan 08, 2010 6:51 pm

TELL THEM YOU DO NOT WANT THE TRANSMISSION UPDATE!!!! YES I AM YELLING!! :dizzy:

The F37, once done, cannot be undone. There are some working to try to crack the code, but so far there is no fix. Tell them that if you start having trans problems, you will bring it back for the updated TC, pump, and flash. (If they are a cool dealer that you have a relationship with, maybe they would replace the TC and pump without doing the flash)

Seriously there are some on this board that will pay you mucho dinero for your un-neutered TCM. . .

How do you (or they) define a "major" oil leak? If it is from high on the driver's side, it may be from the CCV puck, rather than a gasket. Do you have pictures?

Welcome to the club... and LOST!

as others have said...

DO NOTDO NOT!!!!ALLOW YOUR DEALER NEAR THE JEEP WITH A DRB-III WITHOUT SWAPPING YOUR TCM FIRST!

The last few non F37 TCM's on ebay have sold for over $600 each. They are worth their weight in gold, and once they are neutered, you can NEVER get the original tune back. Use my video, and the information in this thread - viewtopic.php?f=5&t=48911 - to see if your TCM is not F37 or not. If it does not have the F37 flash... beg, buy, barrow, or steal an already ruined TCM and swap it out before you go in for service.

Regardless of what you tell the service writer, the word may be never given to the tech, OR just ignored in the "notes."

The whole Drivers side of the motor is covered with oil. It seems like a major leak to me... I could be wrong.

geordi · **Posted:** Fri Jan 08, 2010 9:52 pm

It could very likely be a blown CAC hose. This is your hose from the intercooler to the engine, and it will degrade (when stock) b/c of the CCV pumping oil mist into the intake lines. The hose won't always have a hole in it (yet) but DOES become porous and weeps oil everywhere. Give the engine a GOOD cleaning with foaming engine cleaner (like 80 cents per can in WalMart) and wash the sludge off, then you should be able to see if there really IS a leak.

Given the light smoking under acceleration you described, this is very likely. Before you take it back to the steale. . I mean, dealer - remove the hose on the driver's side of the engine that runs from the intercooler to the intake elbow. Clean it well with dishwashing detergent and warm water, and examine it closely for any leaks. Follow geordi's advice on the foaming engine cleaner, reinstall the hose, and you will see where the leak is coming from if it is on the engine or on the hose. That will save you beaucoup $$$ on the dealer "experimenting" trying to find the leak and disassembling and/ or replacing parts that don't need to be replaced.

If it is the hose, a new set of Samco hoses that hold up much better than OEM are available for about $300. Replacement OEM's are about $250 from Mopar Parts America.

Joe Romas · **Posted:** Sat Jan 09, 2010 9:03 pm

If it is a hose be advised the ones you'll get from the dealer are updated ones that seem to cure the problem. Also the Samco hoses are not perfect either :frankie:

And you really only need to replace the bad one for now if $$ are a problem :mrgreen:
