15 degrees max. Use 91 octane.
I think tkyan was talking about GA16 timing. Stock GA16 timing is 8 deg and you can advance up to 15 deg with premium gas. Yeah, it says BigHitter23's car is a 99 SE-Limited. That's the SR20DE car. So stock timing is 15 and you can advance up to 19 deg..Black200SXSER said:
WHAT..? Dude...if you have a stock ECU, you can run up to 19 degrees on 91 octane. Dyno testing will tell you were the most power is for timing degree. If you have JWT ecu, then you want 15...
If you dont know the answer...please dont post.
