the best I've done is 14.1, that was with a stage 1 unichip, up pipe. I had a MBC, but I didn't know that some how the tubing split, so I dont know if that means I have a LOT of boost or low boost levels. Since then I've fixed the boost controller and added a Downpipe and hopefully a catback exhaust. I would love to see the 13's but the night I went to CAP the heavy modified cars were only pulling 13.8s and one guy did a 13.6
I think I have a lot to work on.
