New Gears..... Update!
I posted here several weeks ago about swapping out the gears in my 2005 GMC Sierra 1500 SLE RWD with 5.3L. I had recently purchased a 21 foot Gulfstream Ameri-Lite that had a listed dry weight of 321...

the tune was a success. There are no hard copies of test results. What I saw on his website were screen captures. The tune added 14 hp, changed how and when the transmission shifts, better throttle response, removed torque management, AFM, fixed the ABS and BRAKE lights, even did something with the fan because the engine runs cooler now and I'm more aware of the fan when at idle light at a stoplight. I downloaded an app with a GPS speed and it's right on the money with my truck's speedo.
The biggest difference is the way it drives now. I had to leave right after the tune because I was at a campground that didn't allow stays over 2 weeks and I'd been there 16 days already so I hooked up and headed to Texas immediately afterwards. I left the transmission in OD most of the time with Tow/Haul engaged the entire trip. There are a few hills coming into San Antonio that I put it in 3rd and just let it rev about 3200 rpm's at 65 mph. At 70 mph in OD with Tow/Haul on, it cruises about 2300 rpm's.
Bottom line: I'm very happy with the way it handled the trailer. Even on the low inclines, I could accelerate if it was in 3rd without full throttle and in OD if I kept the pedal to the metal.
