Stage II ghetto turbo on mine (RCC), Intercooler, built by Dennis (Motor Head) in 2006. I am running the base map, Microtech, no Power Commander needed. Makes all kinds of HP, great system. Recently had it at Lee's for a tune and we tried a power commander, didn't see any real gains. I had injector issues because the bike sat unused for about three years. Had the injectors cleaned at MPS and it runs great.
