I believe in NY you can have 1 out of the 5 stages of readiness "not ready". This is probably how my silverado SS and Audi S4 are tuned. My 2001 wrangler TJ didn't have a tuner to get rid of the O2 CEL and the defoulers didn't work on that since I had the ******* "California" engine in it for some reason so I had to splice a 02 simulator resistor into the wiring harness of the ECU. I do not want to go this route with the mustang since its so new. What tune would you guys recommend for the money. Car has basic aftermarket bolt ons. Thanks in advance.
