Alright I will see if that helps do you think the rb #6 glowplugs will work better than the 99's. Well Im going to continue using trinity monster horsepower 30% fuel and see if its good. So your saying that the RB are basically all like this from the beginning that the engine tries to cut out while trying to hit high speeds? I hope your right I would hate to put too much fuel through the engine for still poor results. Dont worry about the pipe it is temporary for now I was thinking about getting a JP-1 and some power racing filter elements along with a mugen airfilter set.
