^^^^^. A email tune ,works but your better off spending the extra cash to throw it up on the dyno,and get it tuned...that way it's based off of your truck,not anyone else's.. Every truck,and motor is a little bit different,there can be as much as 20-30 hp difference between stock trucks....believe it or not some trucks from factory may have as little as 9 -10lbs of boost while others will have as much as 14 lbs of boost...
There are are lots of good tuners here in Houston ,many not on the forum..So if you have a tuner already speak to them,if not LET is local and has a good rep...
He also supplies other shops with tunes,and turbos,if that helps...
