I don't see how PI is lowering IAT2 when the injectors are past the temp sensors? Are you spinning the 2300 as hard as you were on the old Camaro? I think what you could be seeing is the Ethanol producing lower EGT's and the engine is running cooler overall?

Fwiw, my car trapped 136 last year on 18.5 degrees timing and E40 fuel @ 10psi. I hope to see some gains with 20 degrees and E60 when it cools down a little. I am not going to push timing any higher on a SBE LT1.

Had the reflex controller been available 6 months ago, I would have probably switched to the PI setup instead of buying +30 injectors. I wasn't sold on the MAF fusion controller, but the reflex looks legit and easy to tune.
