I just got back from the tuner and am in search of a 90mm "Silver" blade C6 05 throttle body for my fast92 that I installed on my 02 corvette, I have a 90mm ac delco on there now unfortunately its a gold blade and they open opposite direction and keeps throwing code and going into limp mode. Anyone know of a reasonable priced place to get one or have a part number to go by ?? thanks in advance
