2001 GMC Sierra 4.8

Hi, I just received my new Predator U7198. What is the best tune for my truck when pulling a camper? It is 4x4 ext. cab and I have a K&N cold air intake, cat back exhaust, and a throttle body spacer. Is there any perramiters I should also change? If I have 90 octane, which is the best tune the 87 or the 93? Would changing the torque management help with pulling power? Thank you for any help you could be.

I would use the 87octane tune for pulling the camper. I would turn the first 2 TM parameters to OFF and you should be all set.
