Engine stop start disabler, as well as cylinder shut down
I bought a stop start disabler from them.I have a Cadillac that drove me nuts when the engine shut down at stop lights. My chip worked great and also stopped the engine from shutting some off cylinders. I did have an intermittent problem ,contacted them and with no hesitation took care of me. They are highly recommended for a great line of products and superior customer service
