You can do that and it would be a very accurate mail order tune since Nelson would be able to view actual logs of how your truck is reacting to his tune allowing him to make minor tweaks to get it dialed in. You would record runs in your truck with HP called "logs" and email them to Nelson to look at. Nelson will then make adjustments and send back to you to upload in HP and into your truck. The down side is you have to buy a tune from Allen + HP Tuners but it would save you a drive to Allen's shop. Plus, I'm not sure how many times Allen will send files back and forth before he starts charging you for them. That would be something you would have to work out with him.
