What do your boost targets and wastegate duty cycle targets look like the 100% columns? Your wastegate duty cycles are increasing towards redline as your boost is falling off. There could be a couple of reasons for this. I'm curious to see what your map looks like first.

Also, your car appears to be pulling timing in a few places (at 4200 rpm and then at 5000 as wrxblubayou said). It would be good to smooth out your timing curve a bit so that it's non-decreasing once you hit peak load.

Are you running on 91 octane gas?

Thanks,
Mike

Im not sure what you mean. As for a map....I just have the off the shelf cobb vf34 91 octane map. The only way to smooth out the ignition curve is to have i protuned right? I am running 92 octane gas.
