Might be a typo, but I think you would want to DEcrease fuel consumption when pulling, wouldn't you? Back to the real issue, I have a TST PM3 I use and it works great, but I don't tow alot. I hear the Smarty has helped with fuel mileage for a lot of people, would imagine on the right setting it would tow well also. Also, since this is your first post, I would fill out your signature with everything about your truck, this helps everyone know what you have done, so when you have questions like this, we can give the best advice possible. Other than that, welcome to the site!
