When you have a tuner like SCT or EDGE, Banks, Diablo etc.... if you uninstall it is there any way to tell it has been tuned before. Or is it safe to assume there is no trace. what about the equipment like with the ege do you have to take out the thermocouple for the pyro and the whole harness or do you just say that was for a guage. i know its getting pretty ridiculous with chevy i ran around with them for a while trying to get injectors finally when they gave in they said they were going to charge me 80 bucks an hour to do my injectors because my truck was lifted and they would have to go up and down a step stool. I pretty much told them to eat it, and went to the Ford dealership and traded the piece of s&*! in.
