Went to the dyno today trying to tune my car for 23psi, but it was such a pain in the butt because of a rich spot @ 4k rpm that went below 10:1 a/f ratio. I finally got a decent a/f around 21psi. It is obvious that a new set of chips and MAF is needed to try higher boost levels.

lart, i would be interested to see the festiva vs your car 40-110. You did 40-110 granny shifting 3rd in about 12 seconds, i did 40-110 in just about 12 seconds granny shifting 3rd as well.

ehall, guns and rolex, thanks.
Ian, I think I might have made a mistake it wasn't 40-110 but 40-120 shifting about 5800 rpms.
Hally, I am using the pro-M maf aka Lindsey digital maf, when making changes I have to guess the rpm range that I want to change.

1st off Nice sheet.
I have the Super 61, Dual port wastegate, MBC, Authority MAF, Mafterburner, 48# injectors, LR chips, 4 inch exhaust, Stage 2 intercooler, and Stage 2 head. Headers and crossover are stock. My dyno runs at 16, 18, and 20 produced 350, 375, and 400 rwhp respectively.
I think you should be able to get more power with chips tuned for your MAF and shouldn't have to replace the MAF. When LR was tuning my car they hit a 350 hp wall and were able to tune it out with my now outdated chips and MAF using the MAFterBurner, Adjustable FPR, and sizing injectors to work at closer to stock fuel pressures at the higher output levels.
