what is the difference in....
 

a 99 ford powerstroke and a 99.5 ford powerstroke? just noticing a few things listed for 99.5's and didn't know what the difference was


thanks Benjamin

This has some pretty good details.

The TheDieselStop.Com 1999-up FAQ

Also I'm 100% sure on this so don't quote me, But i think the early 99 had non-wastegated turbos and the 99.5^ did. But Like I said. I'm not sure.

i think the pre 99.5 had different injectors and the smaller 15*hpop but im not really sure, im probly wrong lol

i read over that and i noticed something odd.... on my passenger valve cover there is a label that has 1999 and it shows BHP @2700 rpm being 250hp. why would that be? i'll take a pic of it when i pull the v/c off to check the injectors again.....

my 97 says 215hp

I think the differance is the 99.5 came with a bigger GARRET TURBO !!!!:ok1:

i have a late 99 and ive heard diff turbos no wastegate uhm....crap i dont know....

my turbo says garret on it and it has the wastegate actuator (well i think it did kind of behind the turbo close to the firewall w/a hose coming off it like my Dodge)

so i pulled the V/C last night to check the injectors that are bad...... this is the passenger side valve cover.

1999 model, 250HP @ 2700 RPM

I'll Check on my buddies 99 and see what his says. His is supposed to be a 99.5 becuase it has a build date of April of 99 however when he dot his DP chip the guy sent him a 99.5 file and the truck didn't run right. Turns out the computer on his truck is from an early 99. Go figure. I'm still not sure whats up there. Whats the manufacteror date on your truck? It should be on the tag on the door jamb on the driver side.
