Just want to share an experience.
Took my stang to the shop the other day to get it dynoed and tuned after I found it it was only $60/hour for dyno time.
Currently, my car has showerhead 36lb injectors and they are dumping way, way too much fuel into the motor, even on top of the rpm range with 9lbs of boost. Our first run we made 360hp@5200rpm at the rear wheels. By cutting the fuel pressure and removing the custom computer chip we made 448hp at the rear wheels, 5900rpm. Not too shabby, but still way, way too rich. At least the fuel to air reading was on the scale that time. This is probably the source of my 20mpg highway gas mileage.
The guys that do nothing but work on 5.0 fords at the shop swear that by implementing 24 or 30lb injectors, an FMU (fuel management unit) that changes fuel pressure under boost, burning a different computer chip, and 2 hours of labor I can safely have 500-525hp at the rear wheels, and close to 575hp if we lean it out close to perfect. They want $535 to do everything, including a few dyno runs when they are done. The seat of the pants difference between 350hp and 450hp is insane. I think another 50-75hp would be noticable in gears above 2nd.
