I use the 91 octane tune and it seems to give me a little more seat of the pants omph. The mileage in the winter averages around 17 mpg on the highway. However I don't drive very much anymore, just to the VA for medical treatment and home, 210 miles round trip.

I'm using the 93 tune, it's great. Just like the 91 tune, you're not supposed to tow or haul with it due to all the timing advance. That's the only drawback but I rarely have a lot of weight in the truck anyway, it's usually less than 500 lb and I don't worry about that. During periods where I am often hauling loads I'll switch to the 91 tune and still run 93 octane and this works out well. When towing heavy loads I used to run the tow tune, but it seems like most people run the 87 tune on 91 or 93 octane with good results.

Nothing like that here (I use superchips)

Now there is some "jerking" such as a firmer shift due to the trans tuning and disabling torque management....but that's just a firmer shift, not "jerking".
