definitely get the ECM... double check the harness just in case there is a piggy back chip in-line in the harness. With the Whipple chargers you either chipped it, or sent your ECU back in to get modded. The other thing you can look at doing is changing to a smaller pulley and installing a 454 throttle body but you are going to need to find a smart guy with the ECU. The guys at Whipple might be able to help point you in the right direction.
