I use the standard 210 as well, and also tow VERY heavy at times. Definitely past rated capacity.

The 210 Tow Performance is designed for heavy towing. I would use that and also put the truck in tow/haul.

I understand that the 210 TP is made for towing, but unloaded the shifting is brutal! Is there any reason why using the regular 210 for towing heavy isn't a good idea? Just curious as that's the tune I always use

i get better fuel milage on reg 210 tranny temps never get over 190 egts might hit 1100 when accelerating or on a up hill grade only difference i see is fuel mileage between the 2 has anyone else tried or like another tune more

The shifting is brutal because the line pressure is really high in order to keep the clutches from burning up under heavy load stress. Since the 210 tune has smooth shifting, a heavy load could potentially put unwanted stress on the clutches. The 210 tune also has some extra safety settings built in to it for towing.

I thought that the safeties were built in all of the tunes below 250? What different safety settings exist between the 210 regular/tow? I have never pulled over 10,000 with the 210 regular, but always liked the shifting/performance...Am I messing up (always use t/h)? Isn't the line pressure in the 210 regular higher than stock? Sorry about all of the questions.

Jeff,

Is one were pulling let's say 5klbs; what would the ideal tune be to run w/the spartan? I don't want neck jarring shifts....

They are, but the 210 tow has earlier engine fan settings for coolant and oil temps.

You could tow 5K with the the regular 210.

I hope you can tow more than 5k with the regular 210, because I've towed well over 20k pounds with it
