Towing ??s

[BigSur]

I wanted to follow up to this thread b/c I have a related question.

I have a small popup camper that weighs awround 1400 lbs.....I "think". I don't think I'm putting an extra 600lbs in to get over the 1 ton mark, but then again...I've never weighed my stuff.

I'm wondering if I should switch to my tow tune for this? My confusion is that my 87 performance tune has higher shift points and basically runs better overall than my tow tune, so I'd rather not change. I've towed once so far with the performance tune....no problems that I was aware of.
