Hello folks, been tuning this GS for a few and stumped!, It runs excellent but not much more power (mustang dyno and showing 338/340tq at the wheel UPT TO 6100RPM),..a couple things:
*1 thing I am noticing is a DROP in spark advance when in WOT(to the tune of *8 degress) with commanded from 14-15
* I have the map sensor set for NA-MAP...I have changed that to Sc and SC-tiap with no change...I am under the impression with 8 PSI we would run with MAP
*Everything on the car is stock except for the "maggie"..
*AFR is 12.5/12.8 AFTER CAT!....(only place i HAVE IS THE REAR 02)(would we push that to 13.8 to comp for CAT?
*Did a Myriad of changes to no avail.
could this be a timing problem or am I just too rich and not know it due to having the wideband behind the cat??
Thank you in advance for your help!
