I've heard of him from racingvette, but i don't know him personally. He's claiming that a stock z with his CAI and tune will put down 500rwhp...he alsonhas a forum teamzr1.com that bashes a bunch of vendors like LG AND Vararam. My car is putting down 505rwhp right now with lg headers and vararam intake and tune. I'm not really sure who to trust on that website. My z06 is running really good though with my lg headers and vararam intake.Anyone heard of him and know if they are still in business?
