I know its a free upgrade, but is it really worth it? For me the drive is about 2.5 hours. Right now I just have the Stage 1 flash on 93 octane. Not to long after I got chipped I put in an intake, testpipe, downpipe, and awe exhaust. Is it worth the drive to get flashed to Stage 2? Will I feel a difference? your input would be appriciated.
