you would get back on this site in a month and bad mouth JWT products. Maybe thats what Z1 Wants, who knows? Also, its very interesting that when Ash was working for Z1 he would dyno tune a 530bb car and make less then 400rwhp. BUT now all the sudden the same Ash dyno tunes a sport500 car and makes close to 470rwhp, interesting. I feel sorry for the next person buying those turbos from Z1 Thinking that hes got a set of sp500s. But im glad it worked out for you Rob.
