Im about to order a APR k04 kit and a Meth kit for my GTI 2010.
Im planning to run APR k04 100 octane file with the meth and 91 fuel pump but I dont know if its safe for the Stock engine . I cant find any information about the k04 100 octane file anywhere.
I have all the supporting mods for this setup (intercooler , turbo back , intake , clutch).
