CEL and no acceleration

I just contacted him on FB now. I wanted to have more troubleshooting done at first to eliminate common faults before contacting a tuner to help me figure it out even further.

The good thing about him is he'll help you troubleshoot

Yes he does want to help me! I just talked to him and he thinks the problem is more than likely in the tune. He would check out my data logs and even send me a stock tune file. Thank you for recommending me Eugene Turkov, he really seems like a nice guy. I think I'm in good hands now.

He is always willing to help. You are in good hands

Remove the tune and see if the problem is still there.

Do you have test pipes?

That's what Eugene suggested actually. I have high flow cats, catback and Z1 intakes.

Rusty

The O2 sensor could have gotten damaged during the install of the cats. A lot of times, if a impact gun was used on the bolts before removing the sensors. The vibrations from the gun will kill the sensors. A lot of people on here have had that issue.

Thing is my car was perfectly working before going to the tuning shop so I do not think the dealership did a wrong installation as I remember seeing him hand tight the sensors then use a wrench to torque it. Could o2 sensors break on a dyno due to heat or vibration transmitted to the car from the tow straps?

Rusty

I don't think so. It would have to be a really lean, or really rich mixture to foul the sensors.

Any time I hear about limp mode/loss of power problems, I have flashbacks. I was having limp mode problems a couple years ago. Car would go into limp randomly. Sometimes it would run fine for days and sometimes would happen three minutes after starting the car. The only thing that seemed to temporarily fix the problem was let it sit overnight, disconnect battery for awhile, or use an app to clear any CELs (sometimes there were some, sometimes there weren't). All options inconvenient. As before, it would go back into limp after un undetermined time for undetermined reasons. Of all the things it could have/should have been, and all the things I tinkered with or swapped, it turned out to be the throttle bodies. I took them off and they looked spotless, but I hit them with some throttle body cleaner anyways and put them back on and now years later haven't had the problem come back once. Can't say if it will help your problem, but a couple dollars for a can of cleaner and 10 minutes of work won't hurt anything.
