I need to go through and smooth it out to see if that will help.
Holding the car at a steady 2,000 rpm it will do about 13.5 - 13.8 AFR all day though.

I dropped fuel pressure to 40psi at the rail and 8ms master and 15% trim got it going. I need to bump it up to 9ms master and 2% trim to get it finer tuned.

That good news Layvon! That sounds a bit rich at a steady 2k. It seems like it should be 14.5- 14.7 AFR. Are you trails ring it to PnL? How much time did you book with Junior to do the tune or was it just a start time?
