Anyone with a NBS Chevy/GMC I highly reccomend a custom tuned pcm....with my crappy 99' computer i was at 12 mpg city 13.5city/highway. After upgrading to a 2001 computer and having it tuned for performance/economy I now average 14 in town and 15-17 highway, plus the performance increase is about .4 in the quarter mile.
