just wondering where, how much and turn around time...

i can't remember who i read had it done... (Official Mugen Distributors)

They do it for $150, which includes boring out 4mm, installing a larger throttle plate, recalibrating the TPS, and doing a full polish. I've got a TB on the way, and plan on sending it to King MS to have it done. I forget what it says about turnaround time though.
