[QUOTE="ckrueg, post: 1465580, member: 12403"] I seem to do pretty good with my 16. went from about 17 stock on the highway to 20 after weight loss. And I also switched from oem tires to 295 65 r20s. Im running the Patriot 500 tune with 2nd gear lockup. I noticed the best improvement while the engine was cold. It seemed the factory tune would dump the fuel with late timing to warm the exhaust. I am running full torque and switched to LE 8854, so I'm sure that helped. [/QUOTE]
