I have a '99 F250 with VIN of 1FTNW21F0XED29703 with a manufacture date of 01/99. I am looking to do several turbo/tuner upgrades to this truck but am not sure if it qualifies as a 1999.5 or the older 1999. Basically, what is the difference between the two and can anyone tell me which flavor I have?

Thanks very much in advance - this is a killer forum, I'm glad to be a member!

 

Their was a thred that had many things listed in it that was in regards to this same question. Did you try and search function?

 

I have a early 99, anything before like 12/7 or 12/8 99 is considered early diesel. shares some similarities with the 98 diesels. there were engineering revisions to it. I know my turbo y-pipe from the manifolds and the turbo exhaust housing are different. I've never done a search or comparison to find out all the differences. But with a 99.5 you should have plenty of parts and upgrade options, since that engineering spec ran until 2003.

quick and simple way to tell. if your Powerstroke V8 badge is near the headlight on the 1/4 panel, its an early 99. if it is below the mirror on the door, you have a late 99.

 

Thanks, folks. I swear I did several searches earlier in the day for this info & no results were returned!?! Satellite internet not quite ready for prime time I think.

Looks like I have the "later" '99 unit...

Once again - excellent website/forum here. Great moderation and nothing but useful information.
