Bored out your throttle body? i am with xj on this one, you had to get a new butterfly valve to fit the larger diameter tb. Or maybe i don't understand what you did.

I guess I should have said. Ported and polished. Out the step down under the butterfly but I took out the flap and rod rougher up finish with scotchbrite then polished the whole inside. Of throttlebody to mirror finish and also polished the flap.
