i agree, it could have been wheel spin but also right where you get that spike your AFR graph also goes extremely rich almost making me think best rich torque. Im thinking your afr at that point is what may be causing the spike. but i cant say for sure as i didnt tune it or have the logs to see what was going on. Numbers look great and if your not seeing knock and car is running smoothly you should be good. and that graph is not going to be perfectly smooth without alot of smoothing factor done too it. id say unless your having issues enjoy the car!

 

stock at 4500ft elevation on the crappiest 91oct with nothing but a tune i put down 316/330... on a brandnew just finished calibrations dynojet... granted not a mustang but still... and at smoothing of 1 my graph peaked at 3750 and stayed flat til redline... careful tuning yields results..

 

Thanks for the input guys im very happy with how it feels, ill probably be getting another tune soon after more mods hehe

 

For Filter value 50 that looks very bumpy, but if your happy man then that's what counts. Maybe its just the 91oct makes it more difficult to smooth the power out

 

I'm running 280 on a conservative tune feels pretty good tho.
