Ok so here is my frustrating story.....
I have an 07 EB and decided to go with the Superchips Cortex 1950 because I thought it would do the following based on my research and pre purchase correspondence with Superchips:
1. Towing Performance Tune
2. Better Gas mileage tune (87 Octane)
3. CAI Tune
4. Tire Size/Speedo Recalibration
Items 1 & 2 worked out, but not 3 & 4. For item 3, Superchips has a CAI tune for the F-150 w/the same 5.4L engine but Sperchips will not let the Expeditions use it (for what seems to be a BS reason to me). Apparently the Cortex 1950 can't do item 4 even though one of their own sales/tech guys told me it would. Hypertech makes a Speedo/Tire Size calibration only unit. I would like to keep the Cortex for the towing tunes (which Hypertech does not have as far as I can tell).
So can I use the engine tunes from Superchips and the speedo calibration unit from Hypertech at the same time?
