Anyone know of a company that makes a chip/ tuner for a 2004 3.7? Tried Superchips and Hypertech websites, didn't find a tune for my engine.

Thanks Thunder- I emailed them. Hopefully they make a tune for my truck. I assume you have one on yours?

 

yeah, he will recommend that you add a 180tstat before he writes the tune. or just tell him you have one.

 

I have the stock tstat. Not sure what temp it is...maybe 190 ish? I'm looking for low end power over top end power, off the line my truck is just ridiculously slow...tall gears dont help (3.55's) but I get great highway mpg so I dont want to go to 3.73's.

Truck doesnt shift into 2nd until about 42 mph, and I can't even chirp the tires even if I hold the brake and load to about 2000 rpm before I launch. I just want my truck to get up and go a little better, more power from 1500-3500 rpm would be great. Above 3500 the truck pulls pretty good, I assume because it revs high (up to 5700) and I have CAI and free flow muffler which are both good for high end power but not so much for torque.

 

you need 4.10 or 4.56 to get some brutal low end. you should put a 180 in there.

 

Yeah but if I get 4.10 gears then my highway mpg goes to shyt. I drive alot on teh interstate and I get 22-23 mpg at 75 I dont want to screw that up. Gas is friggin expensive!!!!!!!
