He is the only one I've actual seen replace a E-prom chip on the board that wasn't the factory ford one. The one that generally has the motorola sticker on it, the majority are caps, transisters and circuit repairs though. The cardone and blue streaks I've had they just swap the processor on to good core boards, didn't even change the caps on a few, most of those where not even fox body boards. Why they remove the pinout stickers or paint over them. They scribe the catch code in the pin out plastic if you open the case on one of those. This was a blue streak with an a9p processor..
