Wife's car had issues today, I had to haul it home on a trailer. I picked up the trailer, pulled it with my performance tuned installed. The transmission didn't really like the trailer- it shuddered a little bit at certain speeds.
The trailer was an 18', extra wide especially for hauling vehicles and it had electric brakes.
Got the car loaded up, installed my towing tune. This is about a 3500 lb car, I got it positioned just right, strapped it down and took off.
The towing tune James Henson made is amazing! The ole mounty pulled like a superduty- I could tell the car was back there, but it was no problem. The shifts were spot on and power was amazing. I found myself running nearly 70 without any effort. My trans temp gauge never got over 190 at the pan, even when towing in OD on flat land.
