99 or 99.5?

I have an earlier 99, production date 7/98. And I can't seem to figure out why my truck has the stuff it has. Th updated airbox vented out the front, correct? It has that one, not the fender well intake. The HP rating on the valve cover is 250hp, not 215, 225, 235 like some, and I thought that wasn't available until late 2000. And If someone can help, how do I know which turbo is on my truck? It will be replaced soon soo I think I might need to know.

Ford modifies the PCM programming, and it does not have to comply with the engine sticker.

the sticker is the rating of the engine on a hydraulic dyno with no accesories attatched. with the early 99 until the power was raised the actual power of the engine dropped to 235hp when it was in the truck with all the accesories bolted to it (Huge Fan).

makes an electric fan look real attractive doesn't it?
