I took my X to a custom dyno tuner in my area, actually the best in the New England area and they strapped my bad boy down for a days fun.

The owner, John was awesome- a real car buff just like out of the Car TV shows like Rides, Horsepower TV, Truckin etc... He had to remove the drive shaft going to my front tires as my truck is a 4x4 Sport. The Ford tuning specialist was called in to adjust a/f ratio's and timing curves. By the way this man tuned the fastest car in the world on 10.5" in slicks, an 88 Ford Mustang Pushing 1183 rwhp. He is only available nights and weekends as he works for MIT during the day as a computer programmer.
They beat my X pretty hard taking it up to 6k rpm for a total of 13 pulls. I was kind of worried because my truck is no spring chicken with 137k mi on the clock. They found A/F ratios where way lean due to the Volant so that was adjusted.
In the end the 4x4 put up a best showing of 160rwhp and 220lb ft of torque on 87 octane. Pretty good numbers seeing as the transfer case is steeling a lot of the engine power. I was told 96-98 GT Mustangs put out 160rwhp
Ah Fungue, the truck really pushes the speedo on the highway with ease. But it still seems a bit lean in the deep rpm ranges 4k and above. I am pretty near convinced that not enough fuel is getting to the injectors, as stated before my fuel pressure measured 28psi at the Schrader valve which I think is low. The friggin dealer said anywhere from 20- 60psi is spec and 28psi is within spec. Sure it is within spec and the truck runs but is it optimal? Another dealer told me 30psi with the vacuum hooked up and 40psi without, 28 sure isn't 40.
My next step is to replace the FPR when the weather warms and go from there or just dump the X and go for the Jeep SRT8, 0-60 in under5 sec
