It's a stock 1-bar MAP and a blow through MAF.

The MAF is a bit jagged but if you look at the TPS, it actually follows it. This was a brake boost, launch, and spinning though 3 gears. He was peddling it the whole time, but when the TPS is flat the MAF levels out. Boost levels where probably all over the place.

You can't peg your MAF like it is

Has it been rescaled for the Twin Pumps?

He needs a 2 bar and is that an Abaco MAF?

I have no experience with fuel pump control modules, so what exactly need to be scaled??

It's a stock MAF. Why does he need a 2-bar?? He would max out a 2-bar too and HP Tuners doesn't have a 2.5-bar patch available for this OS. Any idea why the commanded AFR ratio changes while in PE?? That's really the only question I need answered.

Are you saying I should scale it more?? I was afraid to scale it too much so I figured scaling it back 20% would get us to 16 psi.
