I primarily to on 87-93 and 99-04 Mustangs. I just started looking into creating a tune for my personal car, a 2013 GT. it seems to me that the Sct value file is very aggressive. are tuners even using these as a base starting point? it and 5 degrees of global spark, it also seems to have tables slowing down the knock sensor, Or limiting it. just curious if guys are even using these.
