TX Tahoe Z71

Wanted to get a baseline before the GT2-3 cam went in. She put down 403/453 in 108*, so I was not too disappointed.

The upper red lines are current mods, less the GT2-3 cam and with a really dirty air filter (didn't notice until the cam swap):

The lower blue lines are same as above, but with stock manifolds, Y pipe and cats, 3.3" pulley, 93 tune on 93 gas, stock flex fuel injectors, and 58* weather.

I was expecting more gains from the addition of catless LT's, E85 tune, injectors, and 3 lbs. more boost, BUT it was 50* hotter so not ideal for FI. Truck pulls great though, so I wouldn't care if the dyno read the same, still puts a smile on my face when I hit the skinny pedal




Video to come, have to upload it from camera.

Dyno numbers with new cam to come as well when I have a free weekend. I want to do it with similar weather to get a more accurate comparison.

Were u around beltway yesterday? A supercharged tahoe with 20" SS wheels up front and stock wheels out back hit it next to me while I was doing some logging and thought it might be u.

Cool, I've only seen one other blown Tahoe in Houston (as far as I know), it was an all black NBS and had a "Supercharged" emblem on the liftgate. The one you saw wasn't mine, mine looks completely stock (heat exchanger painted black in the front) and the only things that would give away that is isn't stock are the blower whine, the exhaust noise (which goes through a 7"x12" round then a 22" long magnaflow, so it's quiet just cruising), or the 275/60/17 Hankook Ventus RH06 tires.

Thanks! I wish, still rocking the stock trans and G80 (hopefully TT to be installed within the month), so I can't beat on it too hard

Unfortunately no once the truetrac goes in, I might have to take a trip and see what she has in her
