now for some real answers...
not much that i have found so far.

i swapped my muffler for a smaller higher flow unit
i have a high flow air filter in the stock box (i removed the bug guard on the inlet of the air intake)
i am going to be building a 'power wire' google this, it is used a lot on the dodge/chrysler 4.7 engine and works on the 3.7 too...
a good tune up will go a long way if you havent done that in a while.

and when i save up the money, i will install the 4.11 gears i have to get some of that power back from my 255/70/16 tires.

So new muffler, saved 10lbs and gained 2 horses

"High flow air filter" just letting in more dust into the engine

Power wire......well works on the 4.7 for "seat horses" but I haven't seen a dyno test to proved it yet.

Gears.....honestly best bet.

Or just swap a SBC or SBF and have fun!!!

i have some extra power wires for sale if anyone is interested. posted in the classifieds section

Funny how you think adding a thicker gauge wire is going to give you more HP,it doesn't.May make your stereo sound a bit better but that is it.

Oxygen,fuel,and spark is all that is needed and the 3.7 uses no plug wires so no amount of wire will increase HP,will decrease your back account though.

Its not a battery cable. Nor is it a thicker wire. Im not sure you know what your talking about.

The power wire we speak of adds more fuel. I know its a hard concept for you to understand.

It actually adds resistance to the iat circuit. This tells the PCM that the incoming air is colder than it actually is, this advanced timing, this a bit more power....popular mod on many vehicles, same idea as moving the iat to the intake tube, the air is cooler there than the intake manifold

Just unplug the IAT sensor,instant -40 degree temp reading.

Free

And a CEL

The mod isn't for everyone, that is fine, it is just something to try.

And for the $22 bucks I spent on it.......something to try that actually has people talking about it with the Rams and GCs

People talk about HHO kits but they are just snake oil.

People talk about SFA a KJ but thats just a waste of money also.

Either way Troy, I wouldn't spend my money on SFA a KJ or buy anything from that crook who calls himself Rocklizard. Just like you wouldn't buy snake oil.

At the end of the day, ITS NOT YOUR MONEY.
