Russ8993

I need some input guys, bought my '99 Camaro 3.8L a few months ago, it sat in a garage for a year and a half. I've been running 93 octane in it to kinda clean the fuel system, I replaced the MAF sensor and installed a new fuel filter, MSD ignition and super conductor wires intalled by previous owner, it also has a Jet Power Control Module, I know nothing about these and neither did the previous owner, is this worth keeping installed, and if not, does removing it mess up how the car runs now? Thanks for any help!!!
