I am toying around with the idea of a spacer for my 1988 throttle body. Since I am not aware of anyone selling these, I am gonna make my own. A few ???'s though.
1: What, if any, are the performance gains?
2: What is the thickness of the ones available for the 91+?
3: Also, since we are taking about the TBI, what about boring out the trottle body?
