i think i have the 7747, the data is on the computer in the shop.

I do not have any surge at idle or while cruising, It is smooth as can be. I will look into the async injection.

Talked to my transmission shop today and they feel it could be the controller and I am skeptical of it too. A few months ago it was giving me TPS errors and would not calibrate. MSD had me calibrate the system with the motor running. It would not calibrate with just the ignition on. I think i will have summit ship me a new one and test it.
