I first got my stage I chip back in November of 2005. I got a beta stage II chip with the exhaust in late December of 2005. Keith at APR said I was the first car to get their 91 octane stage II program. I new they had an update for the stage II a couple of months later, but hadn't taken it in until I started getting a "Catalyst System" error code that APR said was linked to the beta version. It was a minor error code caused by the high flow exhaust not heating the sensor fast enough. I could have lived with that if I had known that it would cost me a torque loss to update the software. Sometimes newer isn't better!!!

 

so it's the stage II upgrade program that has the minor error, so is my program ok? or should i take it to the APR dealer and let him take a look at it?
