First time here never used a tuner looking to buy one and do my first tune. Put a 4.0 ford in a 2002 jeep tj and can not get it to start no injectors but motor will start with some gas in intake and stall. i think pats is doing it so i need to know can i trun off pats with your tuner to start off with. I what to use tuner on my jeep first and then use it at work fleet van. i had a ford tack tell me that i can not turn off pats.
