It'd really help if you mentioned some type of power goal and usage.
This is me and a E92 with MMP stage III's. real similar boost, timing, etc. He's on a 7" street and I'm 7.5" race.
I'm relocated and he's on DCI's.
Both of us are fuel only, no meth.
About 19-22psi.
When he pulls away from me, I misfired. My car has issues.
I'm 120,000 factory stock turbos.
