I disabled the O2 sensors before the AI was removed. It greatly reduced popping and reduced the snatchy throttle (but not completely) going from 0% throttle to less than 5% throttle.

Wondering about your left over rubber plugs.I seem to recall reading (maybe on Rat forum) about someone asking the same question and they were told the AI removal kits were for both carbed and EFI models and the plugs were superflous to the EFI models. My memory is a bit vague so I could be mistaken.

BUT did you plug the airbox where you removed the AI tube? One of the plugs should do this if you haven't already plugged it.

Cheers, Richard
