I currently have a 2008 Ford Expedition Eddie Bauer that has had a Saleen supercharger added to it. We have had numerous problems with this mdofication. After what seemed like an eternity and a new engine I might add; we felt we had everything hashed out. Now, though, the shifting is very hard, to the point it almost feels as if your neck may snap. The dealership is saying that is the way it is going to be nothing can be done about it. Is there a modification that perhaps can be done to the transmission to compensate for the increased power being generated?

 

Take it back to the person that dyno tuned it. The shift points and firmness can be adjusted in the tune file.
