I put in a pro-circuit piston, tokyo mods ECU flash, mild porting and a pro-circuit exhaust. I think similar to stock, but more everywhere. It works awesome.

I put in a wiseco 14:1 piston.....needs 94 octane to stop pinging. Also, leaned out idle 2% to get it idling better. I actually like the added power and was able to use a 49 tooth rear sprocket.
