1. I am wondering if I should wait till the mods are done or will the tunes cover these mods w/o throwing and CEL's.

2. The "Fuel Sipper" tune you offer, is this reflashing the FICM, to the tune I am reading about on the forum. Or does it come part of any other tunes you offer, the guy I bought the truck from said Ford reflashed him and his MPG's went down alot that is why he got rid of the truck.

3. I'm curios on the Gryphon, is it 4 tunes and the stock, or 3 tunes and the stock?

1) Muffler is not an issue. EGR can be handled up front if you're planning on removing the EGR.

2) The Fuel Sipper program is a specifically tuned program in and of itself. The FICM mod is something else. When ford reflashed the vehicle, the ECM, TCM and FICM were all done at once. It's the combination of the files Ford uses that causes the vehicles to run poorly. Reprogramming the FICM makes a big diffrerence, but good tuning also makes a difference.

3) 4 tunes plus stock.

Hope this helps.
