Fix check engine light from after market down pipe
2019 gt 53. Previous owner blew up the turbo amd fried a bunch of computer modules with engine tune.
I have replaced everything except the down pipe it’s another 4000.00 for the stock down pipe. The car runs and operates great but I have a check engine light on coming from the second o2 sensor. Is there a way to get past this with out tuning the engine? I am a little scared after what the last tune did to the car……. Is there a “ dummy “ sensor I can plug in or can it be programmed to just accept the downpipe readings? Looking for suggestions if anyone has anything I am all ears. The dealer says the sensor will not affect anything but the engine light is annoying to look at ….

There are spacers that move the sensor further out of the exhaust stream that help in some applications, but I don't know how effective they will be on this car. You can safely tune the car, many people do, I don't see why it would cause damage.

I am a little hesitant I don’t know much about tuning but the last owner fried three computer modules two wiring harnesses and blew up the turbo. Now running stock software again. I don’t know if I could take the chance no one in my area that I know of tuning these
