So, i've been kickin around the idea of running U4.4 in my bike when at the drag strip. My bike has OE header cat delete and mid-pipe delete with slip on, PC5, wideband commander and the usual bolt on suspension stuff for drag racing.
I have a few questions though. A buddy I race with has a gsxr1000, with similar setup as my bike, he runs U4.4 in his and loves it. It seems most people these days are running MR12. I've found they're both oxygenated, MR12 is a 93 octane and U4.4 is 103. Aside from the octane difference and about $10/gal price difference, what are the pros and cons to running U4.4?
Thanks~
