Not bad. There seems to be only one option of a guy here that comes well recommended that has a dyno. I've left word and get no call back, i know hes busy so possibly he doesn't care to make some cash on a tune. Other option is to go with another guy that is reputable but it would be a street tune ($500) however he said he has access to a dyno which I'm not sure what that would end up costing. I'm guessing yours ran real well after the dyno tune both all out and street driving?
