2014 chevy ss sedan E38 A6 BTR stage 2 cam rotofab 2x3 long tubes catless xpipe. Car has not seen closed loop in over 2 years. Tuned with wideband only. I have been driving since cam install for over 2 years and have had to change the lifters to gm performance lifters due to a failed lifter about 30000 ago. I caught it before any lobe damage happened. Also caught a trunion upgrade failure and was able to get most of the needle bearings out with a magnet and did a CHE bushing cconversion on the rockers successfully. I recently put the front O2s back on and ran it in closed loop to see what the fuel trims look like and to see if i could tune the maf sensor with the narrow bands and well i guess ill just have to post a log because shit is just not looking good. But here is my tune91 octa.hpt I will attach a log shortly after my family wakes up. Thank you in advance for any advice. heres a logwtf.hpl
