So I guess I broke the rules and updated my SCTX4 tuner. I bought a 2011 GT and was bringing it back to VA emissions legal. While putting the cats back on I told the tech at the shop it was running rich. When went over the mods the car had and the tune that was in the car. It turns out the guy supposedly installed a 85mm TB but it was stock 80mm but the tune was for a 85mm. When I got home I broke out the tuner and it showed an update which I hit ok on! The tuner froze midway through the update I hooked it to my computer and finished the update. Installed the correct tune on my car and it runs like shit! I’m getting P0300, 0316, 0307, 0308. I was getting P1602 but that seems to have dropped off. So far I have changed out the #8 spark plug, swapped the coils around.
I have searched the forums (the search function is not that reliable) for the codes and a trouble shooting guide without much luck so I have to go through pages of threads just to see the exact search term I used in a thread title. I did find the never update your tuner thread just a little to late.
The last things done besides the tuner fiasco was the cats being installed should I go back to them first and then where?
