Since my torque converter has been replaced and the Eco full torque tune the constant shifting is a thing of the past

Our trailer is around 3500#
Is the full tune and new converter that much of an increase / benefit to towing?
DEFINETLY

http://www.greendieselengineering.com/f ... st/20.pageBasically pre F37 torque peaked at 301 foot pounds at 2k rpms
Post f37 it's limited to 260 from 1400 rpms up to 3k when it starts to drop off naturally.
Full torque Echo goes from 290 at 1400 rpms to 335 at 2k rpms a then starts to drop off.
When towing up a grade you can really feel the torque below 2k rpms now
I also see no need for any transmission reprogram of any type because with my drving I don't think it could be much better.
Additionally on our last trip I got 1.5 to 2 better MPG while towing. That's from 19 to 20.5 mpg. Our trip is from Oh through WVa, Va, and NC for a total of about 700 miles and there's all types of driving from flat land at sea level to I think around 5000 feet above sea level. Also it seems to shifts sooner without the trailer. I've also noticed about the same mpg better from the original TC with the standard Eco tune in my normal driving. When the TC and pump were put in the oil pan had TC clutch material in it at 33k miles.
With my jeep like it should have been I'm now "one happy camper".
