not doubting it said that number but some times there are issues when hitting the rollers. how many pulls? Were they all close to that number? Been around the dyno enough to hear people say they hit x at so and so's dyno but can't come withing 40hp of it on the same brand dyno a week later with same weather. Mine made 354 with rv275's and edge juice. We are talking the difference of about 35hp on injectors.
