The Pro-m 75 bullet meters are notorious for getting bitchy when used with the typical CAI fendermount intakes like the BBK and MAC...the unshielded type can also cause issues. I'm willing to be if you move to a stock box and high flow filter that the A/F falls well into safe range. I myself have seen the reading drop 4 full points going back to the stock box from a MAC. I can only say this for the 75mm bullet and some C&L units...can't say for any of the others. You have more than enough injector at 19 to run safely at or near stock FP setting IMO.

I've got a Pro-M 75mm Bullet MAF as well, it runs kinda funky, maybe I'll swap back in my stock box and see how it runs?

That's what i thought too i figured that the fenderwell intake might have had something to do with it. Can I still use the fenderwell intake if i bump fuel pressure up or will it still screw up? Worst comes to worse i'll go back to the stock air box if i can find one in a junkyard lol.

The problem is the turbulance created by the bend JUST in front of the meter...the wash created causes incorrect readings by the maf..sometimes this can be corrected by clocking the meter (rotating) but most often it's easier to return to the stock box (feeds WAY more than enough air for any 302-306 N/A car) or a nice anderson power pipe

I'm not saying that is the cause...I'm saying that's something I've experienced...you will find no performance loss in returning to the stocker...THAT I can assure you.
