Nice! I like that approach and obviously you get what you pay for. Your printouts -- details, or just power/torque vs RPM curves?
Assuming that my shop is competent, the "after" tune should be fine (and "before" run irrelevant). My suspicion is that they are running into a wall in terms of what the Harley tuner can deliver, and don't want to admit it...
Dyno tunes were before and after torque and horsepower. I was actually there during the last tune and could see the fuel trims etc.
and if they can’t tune the bike with the products they sold you they should’ve never sold you the upgrades. Dyno tuned prior to Upgrades is important because it shows you a baseline of Performance.
