I just bought a 2005 2500 Dodge/Cummins (I'm absolutely new to diesel) and some of friends who own one also, have a difference of opinions on whether or not to put in a performance chip (correct term??). One says right away and the other says wait until I have about 10 K miles on it. Any experts on this?? By the way, I live in Calif. where they will not allow them installed on new trucks.
Thanks for any info. Mike
