FP black and some E85
Knock is always an issue with pump gas. You never know if you are getting true E85 or some other percentage. It would be one thing if I was running VP fuel where you know what your getting everytime, but with E85, you simply do not.
I tuned this evo. We are speaking of an engine as well. A motor is powered by electricity. The tune on this car is very conservative and has plenty of room left to make power. Please do not comment Alligator, as you were not there and have clue what the ignition map looks like. Thanks. Also just to clarify, the boost simply spiked 29psi and held 27psi. We are using a GM solenoid. The injectors were tapped. Another reason why we left the boost alone.
Soon be installing a BR2.3L and SD conversion. I will keep everyone posted. This car is a true street car and very capable of more power.

Also curious about the torque, see how during onset it come up, then rises again 500rpm later? This is not typical in my eyes. Is it a trait of this turbo coming up to full shaft speed or timing just being extra low around 3500-4000?
To everyone that thinks and is acting as if I took 10 degrees out of the ignition map are worthless your thoughts aren't needed. Thank you. I simply took three degrees out and left the tune spot on KNOCK FREE. Still ran 29 psi held 27 psi by redline.
For reference. The igniton map looks like this. 3* at peak torque and 11* at redline.
AFR was a solid flat 11.8 throughout the entire powerband. Any more questions?

Good points here, if I remember correctly, the E75 would have a different burn rate than the E85 and having a little less timing would help if the fuel ends up being not quite what you were tuned on. I know when I was on the dyno I had measured E85, but when I went to the track we had to pull a couple degrees for the "E85" from the pump in Norwalk
