I hpe this is the correct forum for this question, if not please advise.
I have a 2007 5.7 with factory tow package. I use the Durango 95% of the time to tow either a 4000 lb travel trailer or a 3800 lb boat.
I am considering a performance programmer like the flashpac to increase torque and maybe mpg. Before spending $400 I thought I would see if a dodge dealer would consider altering the onboard computer to optimize efficiency for towing. I was told that as I have a tow/haul control installed, the computer would adjust all performance aspects without addition adjustments.
The question then is; Would a programmer be of any use or did the dealership tell me this so I would keep my hands off their product?
Thanks
