Howdy Guys,
Have been browsing the US online stores (bad for my bank balance I know) and have noticed that VF sell 2 different supercharger kits for the VR. One is a "US Spec" kit and the other is, funnily enough, a "NON-US Spec" kit. I imagine the only difference is in the chip? Different fuel octanes etc? If I was to order a kit would I be correct in ordering the "NON-US Spec, OBD1" kit?

Cheers Bruddas
Simon
