Well guys im wondering something that has been bothering me for a while...does advanced timing hurt anything on a boosted car over 15 deg. mines at 15 and has been and probly will stay there, im just wondering cause if your runing 93 or higher, is it gunna be fine? im wondering this becuase i've heard a couple boosted guys telling me they'v ran 20deg at 20 psi and were fine.....let me know what you guys think....
