In the OP's case, sounds like stageIs with a good tow tune PCM reflash is the ideal solution. That would give him about 375hp without worrying about any chip connection problems or a tune that wouldn't work with a load and has the side benefit of being cheaper than a chip. PCM reflash is around $175.
Thats what I really want to do with my superduty. I plan to replace a lot of the plastics in it. I sure as heck dont want to put that cheesy rotary knob on the dash when im trying to make it look better.
A pod near the gauge cluster with a pushbutton/led tune changer would be ok but id rather just have a fancy tune written. Ill buy a few nvk pcm as backups if needed.
