Default Re: MAFT Gen 2 - Anyone?

Hey guys, I'm having some major trouble running at 16+psi.. anytime I go over 15.. the car starts sputtering and stuff.. seems like it has moved from doing that at 17-18 psi, down to 16psi.. weird. I have my AFR tracking across the board set to ~ 14.7 and at WOT it runs pretty good around 12.. -19 on the mainscale... I "believe" I zero'd all the Hi/Mid/Low settings.. I just installed my new fuel pump last week, maybe not getting enough fuel? I pulled a 2nd and 3rd gear log a few days ago, but my palm freaked out.. I had like 81.2% fuel across the board for both pulls... that seemed a bit weird, especially that hi/mid/low were all the same... and that it seemed a bit low.. any suggestions?
