I just received my predator, and went to install it on my 05 300c. I had to do the download for it to work. When I finished the download to the car I installed the 91 octane tune. When I started the car after installing it was running real rough and the check engine light came on. It has a code p1411 now. I tried to reinstall the stock tune and it was doing the same thing. I tried to install the 91 octane tune again, but still the same thing. I put the stock tune back in and have the same issues. Any ideas?
