After adding the Vararam a while back my fuel trims were skewed 12%, that intake did the same on my 2007 Sierra Denali. Could be a lean code especially with today's so called E10. Get your buddy to re-cal the MAF Hz table and virtual VE tables with a wideband, you will notice a tremendous change in driveability, you might be a little lean now @ WOT...

Took the truck to the track tonight....very humid but not impressed. 14.26@100.4mph was my best pass. My truck demands less fuel with the Vararam. Im taking it off and buying or making something better.

Did you check your WOT AFR or retune after adding the intake?

Never even messed with the air/fuel untill after I did the intake. Its got a full tune now. Another thing that is weird is ONLY when im at the track the truck at times will shift very funky like have a huge delay. Does this tranny have an abuse mode or when it gets hot it does this? I think I need to put a cooler on it.
