My M8 Roadking was completely stock and ran good. But it was running very lean. I had to up grade the oil pump and figured it was the perfect time to install a cam, air filter exhaust and a tuner. The Fi 2000 R CL works great. As advertised. I was getting a mil light/O2 sensor high voltage which means rich fuel mix. This tuner is very adjustable and can be dialed in very similar to a carburetor. I like it a lot! Thanks for making a tuner that is easy to install, simple to adjust and and works at a very reasonably priced.
