logs should be done after some WOT pulls. as this ecu will target less right after writing or e.g. after 1-2 WOT pulls. It needs more to make adaptations. Usually stage 1 gives ~1.1 bar (16psi) at ~6200rpm, stage2 gives 1.3 bar (19psi) at the same rpms.

We know Decat release exhaust gases out of the cylinders faster but how can we benefit from that in terms of tuning ?
