I have tried the different tunes on the Predator and all do the same. Especially when passing on interstate, when you get on it the transmission drops 2 gears and SLAMS in to the gear. There is also a large lag when it goes in to the gear. I had to return to the stock tune, afraid that I would damage my drive train. Will the update help fix this or will I have to go to a dealer to get a custom tune?
