I can post more if needed - logs go upto ~110 seconds. In addition, my a/f reading varied from 2.5-2.92 g/s at idle (840 RPM) - started at 2.92, when I stopped the logging at 110 seconds, it was at 2.5. Do all the numbers look good? I ask because I can smell gas/exhaust inside the car, this is after I had KTR check my car for any leaks, didnt see/find any. I am running the k04-015 program, 5 bar fpr (stock injectors), borla exhaust, high flow cat.
