Towing tuner.

Im just had my edge changed into a gryphon and waiting for custom tunes. But the edge towing tune is pretty good. I tow my dads boat occasionally its 6000lbs and without the tune i felt like my truck struggled to get up to speed and hills. With the edge towing tune it made a huge difference. I could accelerate at normal speed without feeling like i was going to break something, it gave it alot of lower RPM grunt. Also the torque converter would stay locked up alot better. I hope the custom tunes are even better. Hope this helps
