Re: 97 Z71 driver/project build
quick update, I have put about 4200 miles on it and maybe the engine is loosening up and breaking in, last few tanks mpg has been 17.8-18.2, I'm tickled and I still haven't gotten an ecm from blackbear yet! hoping to pick up a few tenths more from that and a little more pep. still need to get some pics on here, got a receiver hitch tonight hopefully get it put on this weekend and maybe get it cleaned up.
