When I started with 189, I dropped 10 teeth with full boost. I would take all the timing out of the motor. This will give you better acceleration out of the corners. Then start upping the pinion size for the straight / temp. Keet the motor under 160, or you'll see some drop off at the end of an 8 min race.
What motor brand are you running? 17.5? Lap times?
