I was for quite some time, but near the end they just couldn't get the car running right. I still think their setup and workmanship it great. But need to work on their customer service and tuning. Tuning is always very very rich, over the top so
Currently seeing All Star Tuning, Clint recommended them. Took it there, he cleaned up my e85 tune. Car made same power n 4psi less boost and with a cheaper version (non sucrogen) e85 fuel. And I only got charged $330!! 2hrs dyne time
