What about porting your 90mm throttle?
Ive heard the gains from that can be quite good.
I took to mine with a dremel and file. There is some significant meat that can be take out in front of the blade primarily as well as smoothing the hard lines behind the blade.
You just need to be careful not to damage the area where the blade seals hard to the throttle body.
