I have been thinking about this since I bought my car a year ago. I had asked the question on here if it was worth porting our TB's and really never got any responce. It would be interesting to see if there is any HP improvement.

Try it out and let us all know.

so does that mean that all throttle bodies in non M vehicles are the same size? it's what the website seems to insinuate..

It will give you Sprintbooster like effects. But little to no extra power.

Not really. It just changes the relationship between engine load and throttle opening. With a larger bore, a 10% throttle opening will result in more allowable airflow that the stock TB at the same opening. But at 100%, they will be about the same. Even the perceived gains are small since the DME regulates boost based on applied throttle angle.
