I agree that I would expect to hit 10.9 with Stage 2. Do you recall the DA and temp on your 11.15 run? ET? Hell, post the slip if you have it! Ha.

Speaking of which, I expected the redline to jump from 6500 to 7000 with Stage 1. Was curious if there was any discussion around that - I figured with lighter internal components, the S8/RS7 could handle it.

I'm at Deer sea level and the temps were about a hundred degrees Fahrenheit... SoSo there was probably some some heat soak in there

Also I wouldn't worry too much about the red line going from 6500 / 7000 as it seems there are some power loss up top.... Plus I think the red line is 6800.

As for power loss, it's been a while since I've looked at the curves but I suspect one would need larger turbos to alleviate any flattening of the HP curve at high RMPs. But that increases lag on the low end. No matter, was just curious.
