I was recently asked to come into a local shop and tune a gen v lt vehicle. The shop has a dyno but primarily deals in modular ford stuff and the lt platform is pretty foreign to the owner. Up to this point I've only tuned personal vehicles and friends vehicles. I've gone back and forth on what it means to start tuning quote un quote professionally. I look at stuff in this section and think I'm miles from being "good" then look at hack work other places are putting out and think maybe i'm not so bad. When did you feel comfortable enough to take that plunge?
