NooB question
Posted: Fri Feb 15, 2013 1:40 pm
I have loaded the 89 octane tune on my 2012 Dodge Ram 1500 and it installed no problem. After that worked I installed the 91 octane tune (after fueling up). Should I have went back to the stock tune before I loaded the 91 tune? I am concerned in case I ever need to return the vehicle to stock tuning. Thanks in advance for the reply.
