I had to retune my AE when I went from the 5.7 to 454 throttle body, and again when I went from 5.7 to 7.4 injectors. I was running 61# injectors at 22psi, and I am now running 80# injectors at 18psi. on the 5.7 injectors at one point I had it topping out at over 8000 at 50%, now it is under 5000, but still way more than stock. My build isn't overly aggressive but with the increased plenum volume and larger heads it definitely needed a lot more AE over stock.
Is it cutting out when you hit the throttle? from my experiences it will cutout when it needs more, and stumble when it's too much. I've already had it puffing black smoke out.
