I just picked up a used Super Duty and I want to wake it up a bit. The stock throttle response is pretty sluggish and it feels like it's holding back when I'm towing my camper.
Can anyone recommend a reliable company for custom tunes and aftermarket parts?
Seconding the recommendation above. I've used a couple of different tuners over the years, but those guys really know what they're doing, especially if you tow heavy loads. They write the tunes specifically for your setup and modifications.
