not really, if your not showing any knock retard its OK
If you don't have a knock guage then that will be your next purchase. If you have a laptop get Turbo Link and you will have access to all the infomation that you will need.
what if i dont have either is there a "feeling" i should look for? Ive been on the hunt for a cheap laptop for Turbolink in the car, but no luck yet. Thanks for the reply
turbolink is nice but you can save a lot of $$ w/ a scanmaster...i got a v2.1 on eBay for $135, or you can find em pop up in the parts for sale section
and your boost should be OK, hell when I got my car the boost was at 21PSI w/ stock fueling and nothing but an exhaust im supriised the idiot never blew anything up
