Throttle Body Upgrade

[Akiimu]

I would like to add some horsepower to my ti! Any suggestions on how I should go about upgrading my throttle body? What throttle body to buy or gasket sizing.

If you want to do throttle body it will be more for responsiveness than anything! The m44 is decently well built already, there is not really a part to switch for a easy 10hp. It might gain 1/2hp but not really noticeable.

What I did with my 318ti was just send my throttle body to Maxbore (just google it) to bore out the stock throttle body, and then sent my DME for a tune with Midnight tuning and the car was more fun and responsive . . . but it will still be slow

For some reason my throttle did stick a bit and was annoying when I first got it back from Maxbore, but after a while - months? it acted like the stock one with no issues.
