Welcome to the Jet Performance Powertrain Control Module (PCM) Fan blog. This is a blog that is centered around the fantastic hand held tuner that Jet Products created for the diehard enthusiast.
The idea of this blog is to get real world perspectives about this device, so you will find the basic product information along with reviews gathered from around the net. Feel free to leave your own review in the comments, or send us a message via WP comments. I hope you enjoy the site.
I own an ’03 Mustang GT 5spd; in the next month or so I definitely plan on adding a JET PCM and a K&N cold air intake, and I’m *possibly* going to go as far as a 75mm Accufab throttle body and plenum. My question is, will a Stage 1 PCM handle these mods, or am I in Stage 2 territory?
