I have a 2017 Chevy SS with a 2.9 whipple supercharger installed on it as well as jba long tube headers. The whipple has a 2.750 pulley on it. it has been on this tune for about 2 years and i logged the data and found that i have alot of knock retard when partial throttle knock and its pulling timming. I tryed to pull some timming out and it didnt change it still logged as it was knocking. any ideas on what i can do sc tune with trans 26 tires.hptwith afr.hpl
