Does anyone know how to disable the fuel cutoff.. it only kicks when you pegg the speedo.. well I have different gear ratio's in my 90' lumi 2dr cp 3.1ltr. I hit the fuel cut at 120mph and on the tach I'm only at 2700rpm and I can safely get it up to 5grand... but not at top speed.. I know the tranny is good for 180mph.. any one have any idea's ...... please
