I have zero experience with HP Tuners, only drove the truck while Charlie tuned my Silverado.Sorta. It's a combination of different parameters that will help get you your throttle response.
On the other hand, I have a pretty strong grasp of SCT and Ford tuning concepts. I didn't do my own tuning, but I did hundreds of logs and revisions with Erick over at Leading Edge Tuning on my F-150.
