[QUOTE="Gearhead, post: 131090, member: 503"] Stock truck with intake and exhaust only (stock run was with exhaust and intake already). I'm sure backpressure was getting out of hand and thus a wastegate would have done a lot of good up in the higher RPMs. I could have pushed the race tune with more timing, but i erred to the side of safety instead of that last 5hp i was looking for.... I have all my beta customers lined up so i will be getting those out this weekend. General release will be Nov 1st. [/QUOTE]
