TSPerformance just came out with there MP8 for our CRD. I called them today and Chris at TS said it was a 50-60 hp gain, with about 100 ft/lbs of torque, and is available now.

hmm, 220 hp, 395 ft/lbs....

Would be nice.

Actually, they've been showing the MP-8 on their website for several months now. Someone on another thread has already tried one and gave a report on how it did. Only thing I remember is they said that turned up above a certain point it gave them a check engine light.

If you can stand to wait another 2 or 3 months, several other companies, among them Edge and Bully Dog, are going to be coming out with their CRD hardware, somewhere around March. Then you'll have the luxury of several choices.

Yea, Thats what figure wait a bit cause both Bully Dog and Edge said they were coming out with something soon.

Sure would like that A2 or Evolution Monitor. I can just see the look on my Dealers face when he sees one of those installed.

Thing I like about this module, or the digi-cr is they can both be removed rather quickly before going to the dealer. Dont think its that easy to de install the bully dog or edge.

According the tech at Bully Dog, 60hp and 100 ft/lbs was about the best they could get before the Trans started slipping.

That seems a bit odd...given the other applications this tranny has been used in (Hemi 2500 Dodge) and the abuse it has shown itself to be willing to accept...

Yes but the Hemi can't put 300 lbs of torque to the almost instantly like a CRD can. CRD 2000 rpm max torque vs 5000 rpm for max torque in Hemi, at 3000 rpm a 5.7L Hemi is probably only pulling at most 150 lbs of torque.

I'll hold out for an EDGE product.....I have the Juice w/Attitude on my 2003 Dodge RAM 2500 Crew Cab 4x4 Cummins Turbo Diesel (305/555) and it's great......advertised at 125 RWHP and I got 124 RWHP on the dyno last September. Gauges and power all in one, in-cab adjustability, nice compact unit......along with great quality, too. I've never experienced any check engine lights with either the EZ or the Juice w/Attitude.

Personally I think I'd go w/ a module designed by and for the European diesels. The CRD has much more in common with them in a horsepower/liter ratio than w/ the larger American diesels. The CRD makes WAAY more hp/liter than Cummins et al.

I'd definitely welcome some more torque for towing and improved mileage but someone here did the math and a chipped Cummins makes as much hp/liter as a stock CRD motor. Our engines are already pretty tuned. As they say, YMMV.

CRD hp/liter = 57.1428
CTD hp/liter = 55.0847

2.0581 hp/liter difference is far from waaaay more.

(above figures derived from crank hp figures)

The guy refered to a Ford Power Stroke in the posting for what that is worth.

My figures are based at the flywheel of a stock 325/610 '05 and up CTD engine....not one that has been modded. My 305/555 had 244 RWHP stock....you can figure about a 20% driveline loss at the rear wheels; that being the case, our CRD's will be pushing 128 RWHP if they're lucky. If you figure 368 RWHP on my CTD (modded), that comes to about 460 HP at the crank.....or about 77.961 crank hp/liter modded.....62.372 RWHP/liter.

Or as my friend in Texas refers to them, "Dorf Power Jokes". :lol: :roll:

He worked at a Ford dealership in Wyoming for a while. In so many words, what he saw and learned about the then-current Ford diesels didn't impress him in the least. In particular the two piece injectors which kept failing. He said it was a common occurrence during the winter, when they would move the vehicles around the lot to plow away the snow, to have a brand new Ford Power Stroke suddenly start blowing white smoke out the exhaust.

He always parked about a block away and walked into the dealership. He didn't figure the guy who owned it would appreciate him driving up in a Dodge Cummins. :wink:

I know what you mean, Power Smoke is also another name given to them by fellow Ford owners.

The DigiCR (used by many TDI owners) claims that they only alter timing and fuel pulse amount. Some of the others, at least according to TurboDiesel Register, alter Common Rail pressure, boost and fuel. I'm not sure I want to run the pressure higher than stock, without knowing how much reserve is left. Getting that information from Bosch is something I haven't tried. The FSM claims raising boosts on the CRD will not add power. I infer from that that the ECM defuels when it detects overboosts.

Some of the aftermarket performance boxes feature boost fooling; dependent on the efficiency of the turbo, some additional boost can provide more power, as long as there's some extra fuel. At a certain point, the compressed air becomes too hot and excessive boost becomes less efficient than lower, cooler boost.

You should be considering a 2.75" (, or 3" system if you can get one at a decent price). Make sure it goes ALL the way to the back of the turbo, as most engines this size suffer significantly from restrictions in the cast dump housing.

2.5" is a bit low for the engine power output when you fit a Diesel Performance Tuning Module for more performance.

We are finding that fitting an improved exhaust system with a Diesel Tuning Module modules makes a big difference to drivability and power across the rev range.

Boost alone on a properly tuned diesel should make no difference (because its the fuel that generates the power). However most ECU's will compensate for a small boost increase by increasing the fuelling. Dont expect much change in power as a result. How ever you need be VERY careful trying to bump the boost without appropriate precautions, or you will generate ECU codes from over boost. The over boost is an artifact of the VGT having limited resolution for its adjustment, and have seen as high as an additional 10PSI between ECU controlled adjustments to the ECU. Thats not a good thing.

A small increase in boost will also lower EGT some. Thats a good thing.
