I hand ported my throttle body today and went to the track tonight. The throttle response is awesome.
Previous best time was 12.007 @ 115.2, now with PTB new best is 11.93 @ 115.19 into a 10-15mph head wind.
I guess I am a member of the 11 second club now.
This is the cheapest mod I have done so far with great results!
