tech 2 will pick up all of that. you also have to kinda know where to look, i've never wanted to **** someone over for mods, so i just overlook it. i tend to give a lot of good will and warranty, which sucks cause i get paid half the hours but it helps me sleep at night. it really depends on the tech. no one i work with is out to get people with modded cars. we're all hot rodders too, so we understand.
