I have an unlocked/unmarried Cortex handheld tuner for sale
Nothing wrong with it, I just outgrew it (currently running a 6.2L/cam/milled heads,etc.) and have it sitting in my garage sadly so, I figured why not sell to someone else to use
It really woke the car up when i only had, intake, exhaust, and headers (even kept me from getting a CEL from the headers by using the 93 tune and some O2 spacers)
Will come with original box too, im willing to ship at buyers expense.
Asking $220 OBO
