I bought a 1999 Dodge Ram 3500 that has a BHAF and 4" exhaust a few months back. The problem is that I read the Instruction Manual first :lol:(really I did) and they talk a lot about voiding the warranty.
So i went in town to NAPA and had them check for any problems first, they got a P0602 control module programing error.
The only tuner I have is this new Smarty S03 still wrapped in plastic. What I get from everything I read is if I use this Smarty it will vin # Lock and i won't be able to return to stock cause of the error.
Can any one Help? Do I return Smarty, Pay dealer to reprogram my ECM? How Can I get a stock setting?
