Yep I got the Thumpr syndrome... Mutha Thumpr that its. And its like a bad cough that won't go away.
I want to get rid of it. Too hard to tune for street. I can get it to work, just not the greatest, not very good low-end torque either, it sounds cool, that's just about it.
It's being replaced with a Lunati cam, a little more lift but way better duration to tune with.
