2013 5.3L with Hypertech Tuner For Towing?

[JimHanus]

Bought the Hypertech tuner to be able to adjust speedo, and shift firmness. Works great for both. I'm going to be towing with it for the first time (had towed with a Jeep with 4.7L). Only other change is Volant cold air intake. Contacted Hypertech about what the best changes might be, and got a stock "features" for an answer. Has any one towed with the 5.3L and Hypertech, and could let me know what tune they used or what their experiences were? Thanks, Jim

I tuned a 2000 YUkon XL with the 5.3 using a Hypertech. I put in a regular fuel tune. It helped holding speed in a gear on the highway. Whats useful is the torque around 2500-3500. I liked it but it is not an OH-wow change. Look at the HP charts they supply.
