Congrats on getting to this point. Don't worry if the car takes a dyno session or two to make good numbers, sometimes on the dyno you end up finding little problems that you need to address. What valvesprings and spring pressure are you running? I made 867rwhp dynojet with GT47-88 and 348ci and a/a.

I'm running 8:1 348ci, it was 25psi for 867rwhp. Figure 1psi is making up for the difference between running 9:1 and 8:1. #'s probably equate to 950rwhp for an M6.

I agree with ya there...... my 1st session was crap... as soon as HP started to climb with boost id start to spin on the rollers.... 2nd outing was much better.....
Damn John..... 25psi..... i wonder what mine would do with 8 more psi...... mine did the 842rwhp @ 17 psi....
Is there much more then 25psi left in that turbo????

The 408 should help spooling quite a bit....

PTE says the GT47.88 is good for 25-28 psi.

Unlocked A3.

I'm not sure what your car would do Kyle, it's hard to compare really. You have more cubes and more compression and that probably equates to a couple lbs of boost.

I don't have the dyno sheet handy, maybe Intmd8 or Larry will chime in.

John, thanks for the advice... right now I am struggling with just getting a tuner and a dyno with my car at the same time. FU*K!!! Sorry.. a little frustrated. I dont expect huge numbers at all.. I wanna see what it will do on pump gas before I decide to throw some race gas into her and crank up the boost.

Did you run slicks on your dyno runs? Oh and I am running PP Gold springs... My CR is just over 8.1:1... I want to take it a little slow with the tuning and check back pressure as well. The bad thing is I am just running out of time before I have to leave for Iraq.

Yes, dynoed on 28W's. I did not want to do an iron block and the LS2's were not available when I did this block in 2003.
