brian what I have is a b &m 3600 holeshot it stalls at around 2900-3000 right in there, I talked with tim at jw and he said with my very mild setup , I am right were I need to be, he said he could take my money but a looser vert would hurt my et he said. it might 60 ft better but over all I am good right now with what I have, I thought it was pretty cool he was telling me this and not wasting my money.
