What are your AFRs when it "stutters"?
Do you still have the FTC installed? I set it up as an AFC with vacuum/pressure instead of gauge pressure but I have read the FTC uses the gauge pressure setting. It seems to run fine this way but I am curious which is the 'correct' way. The instructions say vac/pressure but others posted that was incorrect.
