Another point I would like to make and have made before, I always use GM parts, aftermarket parts are designed to "fit" multiple applications and can vary in what they read and how they deliver the information.
the LT5 runs on electronic input and is based off of the MAP sensor for all fueling, GM designed all of the programing off of very specific outputs and the small variations in aftermarket parts can collectively have an effect on the performance of the engine. IMO
