stock ecu. I think I remember you saying the stock ecu max timing under boost was 24-25 degrees? If you are able run 33 degrees under 21psi of boost on PUMP gas , why is JWT reducing timing under boost on his ecus like in my case.
You have double the timing I am running and more boost. 16 degrees verus 33 degrees is a huge variation. I can understand if you did this on super high octane gas. But you said you ran this on pump gas.
