Re: Misfire on throttle but not at idle?
Wow, nice twin setup, I envy you. I do not have turbos but I had the same problem and it turned out to be my Maf. I'm sure your running speed density tho. Can you data log with Holley? If you could see what all your sensors are reading when it stumbles you could probably narrow it down. I've had random issues like this and it's alway because of a loose map, maf, iat sensor or I forgot to plug one of them back in. My bad maf was because I thought I needed a new one for no good reason and the new one I bought was bad so I went back to the original.
