i dont know whats wrong, it all started after I put my headers in right after the first tune. My car has Off road headers and Y, and a tune, Im running the corvette 02's (13111's) I just burned up my second pair coming back from the track...i had my timing upped to 24* and my AF is a 13.1 I think. What could be causing this? bad tune?:bang:

hmm, maybe, im going to call my tuner tomorrow... Maybe I should post this in the tuning section? I honestly love the headers, but i cant find the ones i bought on ebay anymore

Your af is perfect your car is only at 23 timing and I picked it up over twenty to the tires. Your o2 were burnt up when you got here. You may need to look at something other than a tune. I dont even know how you could burn up o2s on a bad tune! Call me with any questions.

yeah, my first thought was my A/F was messed up, but i looked at the chart and it seemed fine, i pulled the o2's and guess what? the 13111's we orderd were not 13111's. some how advanced auto mixed up the wrong sensors in the right box... :bang:
