Bored throttle body injection body?

Anyone ever bore out their throttle body? I'm more interested in engines with throttle body injection.

How did it perform?
Any drivability issues?
Anything else done at the same time of throttle body?
 
The only throttle body injection I am aware of is the 86/87 2.5L. I don't know about the 2.8L. In the US, no XJ's had throttle body on the 4.0L.
 
Okay, I have an '86 2.5L and I am wondering if anyone has bored out their 80's throttle body. I want to know how it effects everyday driving, performance and fuel ecconomy.
 
The experts on this tend to hang out over on Yahoo groups in the 4banger section. I built up a performance 2.5L with tbi about 6 years ago. The biggest improvement in power will be a different cam. The throttlebody does not do that much without a cam and headers.
