Just came across these guys that have performance upgrade packages. Since I'm new to the MB thang, I don't know much about 'em. If you want to know about doing engine mods to your GM vehicle, than I know Ligenfelter is Da Man! I emailed Oberklasse to ask if they have a performance program or chip to use instead of doing the engine mods. I could see doing some intake mods to help the engine breathe better, but I wouldn't consider doing any engine mods till I'm out of warrantee. Anyone ever hear of this company? Here's the link. Later...
