Towing Question.

[04FX4]

Is it ok to tow my trailer a short distance in the 87 performance tune setting? I was also wondering what the difference is between the custom tow tune, and the 87 performance tune would be.

What's a short distance?
Loaded or unloaded?
Difference between the 2?
Shift points and Bills secret recepie!
Jack posted a weight on how much before switching, sorry I can't find it.

Generally, Bill cuts off the weight limit on a performance tune at about 2,500 pounds. Of course, if you're travelling in the mountains, it wouldn't be that high.

Our tow tunes are calibrated for more bottom end torque for pulling; our performance tunes are written for better performance across the entire RPM range, but you'll notice it more on the high end. Depending on what mileage you're currently getting (most of our customers are getting around 14mph when they first contact us) and your driving style, you should see an increase in fuel economy, as well.

Yes it was empty and about 10KHs, worked just fine.

Well, I thought I was up on metric weight units, but I'm danged if I know what "KHs" means. However, between Lars and Corey, you got your answer and looks like you had an uneventful trip!

Possibly, your trailer, when loaded, might be something like mine. About 3600# or 1.6 MT, in which case a custom tow tune would work better for you than the "canned" one, which was designed for towing weights in the 5000#+ category. You wouldn't need quite the low end torque that the canned tune gives and you'd probably get better fuel economy with a custom tow tune.

Yes I also have a custom tow tune. My trailer empty is 4100lbs.
