Kinda simple, just questioning if I may have fueled up with some poor quality fuel in my last fill. The car, 2012 Mustang GT, full exhaust (no cats), cold air intake and a tune.
What type of total timing do these engines see with quality 93 octane typically? For some reason I was thinking that 25-26 degrees seems about right but it looks like near the top of the pull there is some knock activity so it starts to pull a little and I'm only seeing about 21-22 approaching 6k RPM. I have attached a log, it's a 3rd and 4th gear pull. Starts at 2.7 sec and ends at 7.7 sec.
Thanks
