you can either have decent or bad luck with canned tunes. for the most part people seem to have decent luck with ZZP or other canned tunes. But if something goes wrong...something bad will happen lol. as for as your supporting mod list id say its pretty good, i thought you just slapped a pulley on there LOL that woulda been bad. anyways, get a scan gauge and tuning program and try to give yourself a custom tune. or get someone who knows how to tune to help.
