I am soooooo tired of the 3.42's that are in my truck!!!! So I bought a set of Motive 4.10's and a Raytech deluxe installation kit from THunder Racing!! It wont be installed until the end of thd month. Next on the list is a Fuddle 3400 with a 2.5 str and a Zippy shift kit.

Then.. LS1 electric fans, Yella Terra rockers, bbk trottle body hoping for 320ish-330 rwhp. I am also going to use Royal Purple rearend and trans fluid but im sticking witht he MObil 1 5w-30 oil

I would like to be a 12sec na truck

 

Problem though? I had my truck dynoed year ago. All the guys gave my was a sheet giving HP and torque readings. I noticed when it really got hot here that my truck would hesittate stumble sputter from a dead stop? I went out and got a AFR printed off were I got my truck dynoed. It was 16:1 at 3000rpm but it was 13.1 at 6000rpm (perfect) which I believe is way leanat lower rpms! I Called Nelson to get a retune and they supposivly put me at the top of the list 3 weeks ago. I keep calling and all I get is an voice mail!!! I havent talked to anyone and noone has called me back!!!!! I dont know if something is messed up, but im in and out of the house so much there is no point on leaving a voice mail for him to call me back. I just need a retune!!!

 

just send the computer back to them with a notecard in it stating what needs to be done.


Sounds like you have a pretty nice setup, IDK abour the rockers though..
