Lifted 14' 6.2 ran a slow 14.1@97, need some help with tuning issues.
So I took the truck to Lonestar Raceway yesterday and was less than impressed. Even dropping rear tires down to 20psi and heating them up good it would spin well into second gear, so I started launching in 4hi and switching back to 2wd.
My issues are at the beginning of every run IAT is @135*, by the end of the run its only down to 110*. The stock intake SUX, I can't get cold air into the motor which makes timing drop. I averaged 14-14.5* timing through the traps. The headlight on these new trucks doesn't just pop out like they used to.
Also, when I launched in 4hi the throttle stops at 84%, even after its back in 2wd it never would go to 100%. I looked through the tune and can't find anything on this in HPTuners. I would call Jay, but he's on my **** list.
Has anyone seen or solved these issues?
