I have the orginal A&A Procharger kit that used to make 700+ rwhp and last year I upgraded the bracket to the new style he uses on the Vortech head units and with a 8 rib upgrade I am at 771 RWHP. Look over on the Corvette Forum and get yourself a used A&A or ECS kit. I forgot to mention mine was used when I purchased it almost 5 years ago. My buddy just picked up a used A&A kit and LS1 intake and no headers he got 494 RWHP on his 97
