I just do cruising with it and don't care if I can spin the tires, or how fast I can get to the next stop light. I do at least 25 Wednesday night cruise-ins in my area every summer. This cam is the lower level Thumpr, made mostly for the thump, while maintaining good driveability. I certainly got the awesome idle I was looking for. With the bigger Thumprs, I would have to deal with more mods, like the torque converter, etc.
