Hello need some help Please, I attached log and tune, I installed a T76 twin ball bearing turbo on my 5.3 silverado 80 # deka injectors and sheet metal intake, turbo straight threw exhaust. the rest of motor is stock.
I'm trying to improve my tune. I tuned VVE then MAF now tweaking VVE. under 2k runs perfect. but as the log shows if I get on it, the torque went way up but the truck really isn't that fast seems like. maybe it's me but I think I'm missing something.
how can i have so much torque and not really going that fast, it also looked like spark died at 4k whats up with that.
help is greatly appreciated.
