gen 2 busa. I have a Airshifter and Bazzaz Quick Shifter. I just got the Airshifter installed. When I hit my Horn Button to Use the Airshifter my Speedometer aka MPH Guage Shoot up really Quick and then comes back to the Correct MPH. It is shifting into the correct gear. If I use my Quick shifter, the Speedometer does not react the same way. Can anyone explain to me why a Airshifter would cause that?
