I wish I could say the same as most of you guys but with this weird experience I ended up taking mine off after 3 days I don't think anyone would enjoy their ride when their drivetrain feel like is loose every time you hit the throttle.

The tune might be making an existing problem more apparent. Maybe there is a an issue with some play somewhere in your drivetrain that this tune is exploiting due to the increased throttle response and torque at lower RPM. Can you replicate it at all on the stock tune?
