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 ***** 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....

when i got my car back from tuning the timing was at 18*..i do run 94 octane..iw oudl try it but only with a wideband next to me to monitor the a/f

...and a stethoscope on the engine to listen for the engine rattling itself to death...
