Phoenix questions
I am new to the world of diesels. I have an 01 sd ps with a 6spd. What is the difference with the tow tunes? I will do a lot of towing with the truck, about 9k-11k. What tunes should I get? Just want to make it the most driver friendly and need the truck live for a long time. The truck has 4" exhaust, ais intake and egt and boost gauges.
