I also feel like the Alpine tune I have is trying to put too much timing into that portion of the map to give it better low RPM response.

Anyone else deal with this?
I’m running BPM stage 2 and haven’t experienced this...Have you tried installing the stock tune and see how the car runs compared to the Alpine tune?
