How much did you adjust your MAFT after installing a ported Throttle Body??? After installing my Stage 2 Shaner TB, I'm running leaner up top. Before I was on the verge of too lean, but just right for maximum power. Now the TB has pushed me over the edge of leanness....and I'm getting some KR..and pinging.
I'm going to make a MAFT adjustment and see what happens but I was wondering how much you all adjusted your MAFT to correct the addition of a ported TB???

Re: How much did you adjust your MAFT after installing a ported Throttle Body??? I would try +10 % base and see where that gets you full throttle, should be close.

No leaks or anything like that. Scaling back my MAFT's WOT setting from -8% to -6% cut my KR by 75%....I'm gonna wait for it to adjust some more and go from there.
