X-Pipe

Bang for the Buck Page

First, I must mention that I did not have a lot of time to fine tune the Max Tuner for these runs. Secondly, the weather was horrible for trying to tune. The conditions changed rapidly which would change fuel requirements. This being said, are the comparison charts of Bob's (Bad Max) bike in all stock form verses the addition of X-Pipe and some other goodies as described below. These runs of his bike where made on different days. These number could be made slightly better if I would have had a little more time. This is what I consider to be a "streetable" setup. The chart below indicates the horsepower and torque peaks:

Run 15 from 5-23-09: Setup was X-Pipe with a Stock ECU, StarVmax Top Speed Fix, UFO Max Tuner, Small Rear Tire, Air Box Modification and UFO Max Air Filter.

Run 9 from 4-26-09: Stock Bike, Small Rear Tire

Here is a dyno sheet that includes the Evoluzione Air Filter instead of the UFO. I included this one because the AFR was closer to 12.8 in the mid range.
