Talked with Eric last night, and he said, well here:
"It does exactly what we want. The throttle response is increased a lot and helps spool the larger turbo's. It's give us the power for sure. We had two trucks built identical, but one had larger turbo's. The one with larger turbo's was beating the other truck by a couple truck lengths. Installed the FICM on the truck with the smaller turbo's and it beat the other truck by a couple truck lengths."
Sounds good to me, and BTW, that was my FICM! LOL
