you can tune it though. If your running a higher octane gas, you can program the computer to advance the ignition timing. It's been done.

Or you can just advance the distributor. You'd be hard pressed to see more than 5whp gain from this mod though. You can gain more with a standard JWT reprogrammed ECU...but more like 8whp is probable.
