    Current mods: intake, inlet, tmic, straight piped stock cbe, dp, and freektune ots tune.

    I had the dp installed yesterday and flashed the new tune. Everything was fine for roughly 80 miles. Wife took the car to work this morning and said the CEL came on. Had her check it on video chat when she got to work and the reading was:
    PCM no description available, P0137, and P2299. Anyone run across this? The tune is for the exact mods. She doesn't drive hard. She hates going fast.

    P0137 is o2 sensor, either it's not connected properly or you pinched the cable when removed, check connection and replace if needed only use NTK (OEM).

    P2299 not too sure about can happen from pushing brake and gas at same time.

    PCM is just where codes are nestled no worries about that one as they're both PCM codes.

    Hope you got some upgraded hpfp internals for that DP and tune.

    p0137 is band 1 sensor 2 so it is likely your secondary o2 sensor which is not needed on a first gen car and that code can be disabled. If it is second gen sometimes you need to add an o2 bung extension if you delete the cat as they for some reason like to have the second sensor.

    The P2299 might just be a fluke, I would clear it and see if it comes back.

    I forgot to add I do have autotechs. I'll double check that o2 as soon as she gets home for sure. Not sure why they all came on at the same time.

    could also have not been turned off in the tune, worth mentioning to Justin before replacing it if everything seems plugged in and not pinched
