Hi guys, I am pulling my hair out, I’m running Map 0 on the JB4 (stock boost) currently because I’m in Cali and can only get 91 octane. If I go up to Map 1 I seem to get bad pinging even with a bottle of Lucas octane booster in the tank. I just looked at my logs because the car feels a bit sluggish and from what I can see even on stock boost the timing seems to be pulled down to 0 on acceleration. This is all on 91 octane with a full bottle of octane booster????
