I like it. I didnt notice much torque loss and the before and after dyno shows no loss in torque or HP anywhere. Also, if you buy the cams off someone on the board you can sell the ECU for $300 which is what I did. Now you have the cams for about $200 and the install should be 3-5 hrs
Gain was 5 HP and 3 ft lbs. Pretty expensive for what you get but this bike needs more power and torque IMO
