I've tuned a few boosted vehicles and have had really good luck overall but this one is kicking my tail.
I'm working with a P01 with 3 bar. This setup starts making boost early and under mild acceleration at say 32% throttle @ 125kpa then lift to 22% @94kpa to level out it goes very lean to the point that the engine is basically free spinning for a few seconds before picking back up again.
If i add fuel to the really lean cells then the next time when I'm accelerating its extremely rich and chokes down.
I have got to be overlooking something simple but I've been fighting this for a few weeks now and have yet to smooth it out.
I'm posting my tune as well as 2 short log clips.
Thanks guys!
