soo my car runs great, well for the most. There is only one little situation, during some cruising it sometimes goes rich. This really isn't a problem, unless I'm stuck in traffic. Tune is pretty good and it doesn't get lean up top when in WOT, in fact it stays in the 10's up around redline and then hits low to mids 11... soo it's ok in the fuel department.
As some of you know, NGM change the open loop to 35% of throttle, so once I hit 35% throttle the a/f goes down to the 10's,which sometimes bugs me,just because I still want to cruise and have to let go of the gas or press it more so it response better.
I was thinking either replacing the fpr with the stock one...or just lower my fuel pressure. I remember that a PR member (YoYo) lowered his fpr down a couple psi and the car ran great and had more whp at the dyno, but his was NA.
If I lower my fuel pressure, would the reflash and the 1:1 ratio still give it enough fuel up top? or should I just replace it with the stock fpr? I know the only true way to find out is to test it, but I rarely have time to play with the tib.
