Throttle response is a level higher. Working up through the gears feels the same, but acceleration in top gear is different. In stock tune, the motor would seem to be succumbing to a mildly overbearing and retarding vibration. With the new ignition, acceleration uphill feels positively linear. The power doesn't want to bog down.
More twist just gives more go with no complaints, backed up with a perfect bark.
On the straight and level, rolling on in top gear brings the kind of acceleration that says this motor is happy. It just wants to go. This package would be a perfect capper to any other serious mechanical upgrades in a Big Twin. Dynatek also has many other fine products to keep your electrons under precise control. Check them out.
