The TB is not electronic! It is a mechanical device that is actuated by an electric "positioner". If the TB and the MAF sensor are not clean, then a custom tune will not work right. Cleaning these two things is simply part of routine maintenance. If you don't feel competent to do it, take your truck to a dealer!

And, those big, 35 inch feet explain the difference in RPM between a tune and the stock setting (where the truck thinks you have OEM tires).
