[QUOTE="Catmonkey, post: 16415831, member: 124025"] DBW = Drive By Wire. Basically everything that controls the throttle body. There are a significant number of parameters that impact DBW, but there are a handful that should be adjusted for a larger throttle body. Dashpot settings have their own section in SCT's tuning software and really have more to do with coast down throttle modulation. You would tune the throttle body before you need to do anything related to dashpot. An untuned throttle body can result in dashpot issues that could vanish once the throttle body is properly tuned. Adding bigger camshafts into the mix adds another level of complexity. There are CARB compliant supercharger upgrades, but it's an all of nothing thing. AFAIK, Kenne Bell and Whipple are the only games in town with E.O.s. Whatever comes in that kit, MAF, tune, head unit (including pulley diameter) and throttle body are certified as a single unit. You can't mix and match uncertified parts, or use another tune, as it won't be compliant. Manufacturer's spend a lot of money to get parts certified. Just because the Trinity supercharger is certified on the 13-14 GT500, bolting it on a 07-12 would be a violation. Ford Racing even had that disclaimer in their catalog when it was offered. When you see "off-road use" and/or "never to be used on a public highway", it doesn't have an E.O.
