Is the aev procal a good product for my 2014 2 door or is there a better product that won't break the bank
The Procal is a good tool to calibrate your speedo and it has some other functions. If you're looking for performance gains, it won't help you. But for $150, it's nice to have after installing larger tires. I bought mine in October of 2012 because it was the only tool available to calibrate the speedo on 2012+ JKs.
The ProCal works great and is cheap. I have one and like it a lot but, as mentioned, the Flashcal made by Superchips is a bit nicer if only because it has a screen and can read DTC codes.
