I started with a banks kit in 97 just before they came up with the twin ram. Unfortunately, I tossed the dyno specs on my kit. I can swear that the dyno numbers for the twin ram kit was where my dyno numbers used to be for my kit(or within a few hp) and they lowered the numbers for my kit on the new chart to make the twin ram kit artificially higher. They rely on BS and a whole lot of embellishment and sensationalism. The first plate was junk(totally morphed fuel curve) and I thought the next one they sent me was all right until I put the TST plate in. They finally admitted they didn't have much experience with the 215's. If they just would have said that in the first place, I would understand but they srcewed me around for a LONG time and it was clear as day they were totally lost. I got so much run around from them and customer service didn't know jack I TRIED TO BY-PASS THE CUSSING FILTER, I'll NEVER trust anything they say again. Craig
