Bang into the next gear at 7k, same thing. Nose was up in the air. It pulled so hard it was stupid, and it just keep pulling. The whole time I could feel the 325 R888r's slipping ever so slightly in my butt. That was at the 716hp boost setting. The car is just nasty fast. I will save the 21psi setting for a 1/2 mile event. I just don't see the need for it on the street. If you are one of those guys chasing more than 800hp on the street, good luck. You won't use it. Save your money.

Sounds like fun and a blast to drive are you still running the stock final drive ?

Yes, stock 3.69 I believe.

With all that power you're flying threw them gears. Just a suggestion you might like the 3.3 final drive better especially if you plan on doing roll racing I switched to it years ago and love it.

Once I get this tuning sorted out I can join you in flex fuel land I'm stuck on pump gas 93 for now because E85 sensor was not reading during tuning the other day. For now 651whp 548Tq 4 gear pull 5 gear 675 Whp 654 tq. On the dyno 5 gear was approaching 180 MPH before Vince let out.

I have thought about doing this for a long time but I think you have to do a complete pumpkin swap and not all aftermarket LSD work with the auto final drive gears. I know my Wavetrac does not.

I have a 6MT with the Quaife (1.5) LSD with the 3.357 (automatic) gears.

Contacted Z-1 and they put it together for me.

Seemed the way to go at the time.

I am good on the gearing. I think you can only get a Quaife for the auto pumpkin.
