I am selling my 02 PSD F-250 due to needing a bigger towing capacity. So, I bought a brand new 2006 F-350 crew cab 4x4 LWB Dually with 6.0 powerstroke and torque-shift 5 speed tranny to pull my 36ft. Travel Supreme Fifth wheel which weighs about 15k lbs dry and about 18k – 19k loaded. I will not be towing often, but when I do it will be long trips, up to 3k miles. I am looking for a good chip or programmer for the best performance but will be good for towing also. I will change the exhaust if needed to optimize performance and manage EGTs. What suggestions do you guys have. Is the Edge platinum a good way to go?? I haven’t been in the market for performance parts for a diesel in a couple of years so I am not up to speed on the latest products. Thanks in advance. John
