Finally HPTuners has looked our way. Perhaps in the next few weeks we'll be able to turn up the rpm and set it on kill finally.

Then we'll see the difference between stock exhaust and NONE. Via dynographs.

As it is right now, you can stay below 19ish psi and it won't give you any trouble with reduced power mode.


I'm looking into what will be required for stage 2, (there will be upgrade paths from each of my products) now that the ball has possibly begun to roll at HPT.

It will be the same kit +GT3582R, headstuds, valvesprings and retainers.
Possibly a balance shaft delete, I'm not sure.

It will look almost identical to a stage 1, but should be able to make 500whp or more and be a very angry little beastie indeed between 4000-8000RPM. I dont know about you but I just cant wait to see the needle make it's way around ALL of the tach! lol

Id be willing to wager that number comes on pump gas+meth.
