Ahh..OK. I didn't even look into that. I was looking at flashing a 96/97 tune into my old 98 PCM...just as a test. Someone I know was asking if anyone here in Australia could install an EGR deleted tune for them...a d I just wanted to make sure I has a working .Cal file. He'd have to send me his PCM...so there would be no rewiring Necessary. If I were him...I'd just do the 0411 swap...but he doesn't want to.
