I did buy my xcal2 brand new from the box for my truck. What I'm really wondering is, would my problem have been solved by me "unlocking" my own tuner. MY SCT dealer said he did something that I don't have the ability to do...and told me it would've costed more with SCT. He told me he had to clear/reprogram it, thus giving me essentially a new xcal2 with fresh programs. Its just a little frustrating because I am a mechanic myself (a helicopter mechanic)...therefore I know or can catch on very quickly to whats going on. I'm always skeptical with trusting somebody else not mechanically nessecarily, but ethically as to the why's.
