If you're using 91+ octane fuel then theres no point if your car is stock.
It IS possible its still knocking even on 91+ but if you're never push your car, no need to worry. If you ARE hard on the throttle, using 93/94 octane would be ideal unless you can get someone or something to scan.?
no. but it is recommened because of the higher octane its better for the supercharger and you will consume more power.
How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?
You don't have to replace the supercharger you will just have no performence power and bad gas milage, but you will not harm the supercharger. Same thing happen to me, year later I replaced my supercharger belt and supercharger was fine.....dont wait get it fixed dont hurt the GTP!!!!!
means the car has a supercharger
no
