I thought someone else on here posted an 8.6 in the eighth?
either way if you are still running the gmtu upgrade
That pretty much says that you can make as much power with a gmtu as with a hptuner tune?
Are you still running the gmtu?

I really dont appreciate someone who drives and AUTOMATIC telling me to learn to drive. My ss simply puts out more power than a FWD car can handle without slicks. Automatics suck up a lot of power as manuals loose very little. Am I doing something wrong driving by flooring the go pedal in second gear when already going 20mph? (again, will sping the tires, unless I leave the traction control on) all I know is any boost over 20 psi will spin the tires- if you car is not spinning them, then you not making power. My stock clutch would also not hold any boost over 20psi, had to goto a KY clutch. This is with a LSD, intercooler upgrade and downpipe upgrade. I have tried BFG KD2 tires (very loud tread and also can't hold the power) and the best so far are the continental extreme DW. I dumped the stock tires the first month after it was new.
This is my first and last fwd vehicle
I tried kd2s on my vette and hated them
Run drag radials currently on my hhr so cant really compare but before was running Conti ultra summer tires and worked great running 245/40/18s

Initially it was boosting at 25 psi and helping me sit firm into my seat. It has since thrown a CEL as it did before the operation. I think I may have a bad O2 sensor. It won't let me boost over 15 psi until I clear it. Even at 15 it is pretty impressive though. Limping at at 15 psi it still beats the GMTU pretty well

I just posted a graph of a 20g and etc and it dynoed 400/400 basically on 89/91 octane mix along with a lot of other **** factors like fan that didn't blow, spinning, 90* shop temps and iat2s higher then 160-170 lol

Hahn would be wise take note of that instead of letting Vince continue to pretend he has a clue
