Im pretty sure this car may have an exhaust leak somewhere, but looking at the log file, would it indicate something else?
I did a balance test an all were within +/- 2% of each other, except # 5 which was a good 5% off on both tests I ran.
TIA

Your o2 sensors are not even switching. Post your tune, did you mess with the settings? What are the mods? etc. We need info if you want help. What sensors are they? Have you checked for leaks? How does the motor run?

2000 WS6 M6 - LS6 (long block, refreshed top end), 10.8:1 CR, 90 mm ported FAST, Exo-Skel, 227/232 cam, QTP HVMC, EWP, GMMG, 9" w/4.11s
2018 Sierra SLT 5.3L A8 - Airaid intake tube, GM Borla catback, L86 Intake/Ported TB
The motor has an RPM 4 .595/.601 232/236 114lsa cam, RPM stage 3 heads, 42lb SVO injectors, LS6 intake, ported TB, ported MAF, headers, 6 speed.
The motor runs good, just been have some MPG issues. I reverted the tune back to mostly stock (VE, MAF), and it is doing the same thing as with the tune from RPM in it. I fixed the exhaust leak, and it kind of went away. However, when driving, the 02s cycle like they should, and the LTFTs arent anything out of the ordinary. Its just at idle.
