You went with a batmo to help spooling? I heard the 472's are kinda slow, but the batmo should help! Only problem is no more VVT but Still gonna run like a rapped ape.
Good for you man. I can't wait to upgrade my trubo, and get studs and rods. Youve gotta be close to 600hp with that setup, just gonna need more fuel now and you could see 750hp=)
