Ported TBs don't really add a lot of power, 90mm is a lot for our small motors. Its more for throttle response. But how does increasing airflow increase backpressure? What you need is an intake manifold to let your car breathe, and/or a cam.

errrr.... ported throttle bodies add a decent amount of power... It is quite the bottlekneck and porting it would increase the volume allowing more air in and thus increasing the pressure behind it in the intake manifold and heads. but perhaps ten or so horsepower is just peanuts to you : P.
you could take it apart and port it yourself. It's not hard at all and is free assuming you have the dremel. If you get a bigger TB your going to have to port your manifold to take advantage of it or drop on a new manifold. Best to just port what you got but its your call.
