Yeah it should shoot up quickly and both banks in sync, bank 1 is sometimes a bit slower, might be a tired lambda on bank 1, need to check which one that is, grey or black.
Stage 1 now for a little over a week, all seems good so far, almost no timing corrections and if any, it's just one cylinder at a time. Fuel trims all negative, long term ones couple of %, short terms under -10%, maybe because i have the 98ron map, but the fuel is actually 100ron over here?
According to the torque value in the log, i gained 75lb/ft torque, not bad at 15.6psi. And the throttle closure that used to happen on stock map for some reason at 4300rpm is now gone.
Was definitely worth it
