When we arrived at Edelbrock, R&D engineer Doug Stalter had the GTX strapped to the dyno and was working on the base calibrations. This dyno development program resulted in the various fuel and spark maps encoded in the ECU's software for the 440 application. Doug demonstrated the fine-tuning process that can be accomplished by the customer with the supplied calibration module. As we watched what could be accomplished at the push of a button with the electronic engine management system, we were impressed by the ease of tuning changes. Edelbrock has put serious time into the development of these EFI systems; as usual, they've done the homework ahead of time so the customer doesn't have to.
