Man this truck honks! We still have a problem with the truck above 80 that I posted in the tuning section. I feel like its short shifting now because at WOT its shifting at 5400 while still pulling and it dies on the next gear. I feel with the gt2-3 cam it maybe can shift closer to 5800? According to my boost gauge I am making 6-7lbs and after doing many WOT runs and getting on it IAT was at 114 in at 40 deg ambient.

This truck really throws me off because it has so much power that I think its a sports car and i just chuck the thing into corners and it soon reminds me it weighs 6000lbs via lack of steering and braking

Is it bad that already I want to pulley down? Don was trying to convince me to go meth and speed density... he may win

 

it's like crack, only more expensive

 

Meth and Speed density

 

I run SD with no problems. And i shift at around 6K with z06 cam.....

 

how cold do you have to start up in when yo run SD? What is better about it? Do you really feel the difference? I'm just leary about meth and SD with it being my 17k mile/yr DD. I "think" I have it reliable now and I don't wanna push it over the edge

 

If you went to a 2 bar speed density closed loop system it would be just fine.

 

Yup it's just a different way of calculating the amount of air entering the engine.

 

I should probably buy a wideband then incase the meth pump fails and I go lean then...

 

Widebands are always good ideas on modified vehicles

 

Especially when you are tuning your AFR at WOT. Without a wideband you are just guessing because the narrowband O2s arent that accurate at wide open throttle.
