*VID* 76mm turbo 5.3 3rd gen Trans Am @ 5 PSI 75-135 mph rip Hey all. JUST got my 86 TA tuned and running pretty solid. Had 80 lbs injectors which proved to be a PITA to tune, so I swapped them out for 60's and my tuner got it running great Sunday. Ran my brother's 06 bolt on GTO and without brake boosting, I put 2 cars on him at the top of 4th. He went 12.4 at 114 mph in the 1/4, so I am roughly guessing I'm trapping 117-118 mph on 5 PSI. Can't wait to turn this baby up to 12-14 PSI! I'm getting the boost bug BAD now.
Anyways, heres a quick rip starting in 4th gear.

I don't even know what brand they were. Bought them from a sponsor on here and they were listed as just "LS1 80 lbs injectors." My tuner leaned them out basically all the way and the car still idled pig rich, but then got WAY lean under just part throttle cruising. They had a single spray nozzle too, and not the better quad nozzle like the mototron 60's in it now. They were def a bit on the big side anyways. I should have gone with the 60's from the start.

Yes it sure does lol. Gonna play with it around 10 psi soon and see how it feels, and then we'll see what I feel like pushing it to after that. Not sure what a 5.3 will take with a 76mm on it, so I want to play it safe for a bit and really get the tune dialed in.
As far as the 80's, I think I just got a cheap brand honestly. Shouldn't have skimped on them.
