Tired of changing idler pulley bearings. the early kits had too small of an idler so I needed to upgrade to the new design. New bracket. pulley, etc. I also needed to send my chip to JMS. Change MAFs etc.
I was really supprised it runs as good as it does. It's essentially a stock GT with exhaust and gears and judging by the few races I got it seems like it'll run 13.1-13.3.
