[QUOTE="decipha, post: 17032712, member: 74327"] You can't pull codes correctly on a modified tune since no telling what the tuner disabled. Stock tune would be upset with long tubes since the o2's are farther back. There could be any number of reasons why it wont set it. Most common is that the tuner disabled the rear o2s, disabled the checks or didn't adjust the monitors correctly. If the car is not a daily driver you can yank the ecu out and ship it to any reputable tuner who can plug in directly and re-enable it no problem. Would be much easier if your tuner does it for you though. If you get in a bind LMK. [/QUOTE]
