I bought a used MS1 computer off a member of calibersrt4.net and have had it installed for about a week now. At first I thought it felt a bit peppier, but that may be because I had filled up with 93 octane right before as opposed to the usual 91. Max boost at WOT is no higher than it was with the factory pcm. I dunno. I'm beginning to think I may have gotten ripped off. The computer had all the stickers peeled off, and only had MS1 written on it with a Sharpie. Is there any way to tell if it's real or not?
