Thanks as always for the help guys!

I originally had my AFR trackingn setup down around 11.5 too.. but was gettin way rich at like 75%-100% WOT.. like 10.5 and lower!

Im running 16t turbos and 450 injectors with a new walbro pump.. (not hotwired yet) (I will be going 550s possibly next month)

I'm also in blow through now with a 3.5" GM MAF (yes I remembered to change from 3.0 to 3.5 in the settings

) lol

Unfortunately my Palm took a poop on me like right after I pulled the log and didnt save it.. the only thing I can remember is the 81.2 fuel trims and I had a couple knocks, like 3 at one point and 6 at another (neither were at redline) I have to actually re-download the software BACK on to the palm.. all this and I'm hitting opening day at the track on saturday! ahhh!! lol

If all my hi/mid/lows are in fact 0'd out should I just try to make the AFR tracking adjustment and keep it at -19 and try from there? or should I reset and start over? I don't think much else has been changed..

CORRECTION: After going out and setting the AFR to 11.5 across the board, I checked my low/mid/high fuel settings.. I didn't realize not everything was 0'd out... I had +2.0% pretty much across the board in the LOW.. and +5.0% across most of the low to mid rpm ranges in the MID, and mostly 0 in HIGH except for a high rpm -10.0% setting.

Is there anything in the AFR tracking I should also set.. Gain, Aux %, etc? I have not adjusted anything other than the RPM range desired AFRs..
