I love my Jb4 stage 1, BMS, whatever the hell it is called..

Has anyone else put in 100 Octane??

I can say for a fact, that mixing the 100 octane, with the tune, HFC DP and the exhaust, there is a HUGE difference in power..

Not sure exactly why the higher octane really is so much better for your engine, but it is pretty crazy!!!
