HPOP ?

[ward cleaver]

I installed Tony Wildman's chip in my truck and it lights up like ze skyrocket, but the c.e.light comes on. Tony says it's likely the hpop not keeping up.
_______ What year would I look for at the junkyard?

I Found these HPOPS below at Delphi. Which is the one that'll fit my 97 and stop the C.E.L. problem? Tony says I need one from a newer super-duty to put out more power. Do I also need an IPR or can I run the existing one?

I believe the hpop you want is the one off the newer trucks (htp 108). You will be able to use your existing ipr. Probably would be a good idea to buy a rebuild kit and put new o-rings on it while you have it out.

I gots a question... Does the light rest after you turn the engine off and back on?

I have some burns of twildman, and whenever I hit around 30psi the light came on, I read somewhere that the computer will throw the light with boost over 26psi. I never lost power just the light comes on but resets when you turn off the truck. next time it does it, now that I have the AE program, I will see what code is thrown.

You didn't say you lost power.... I may be wrong but if thet HPOP wasn't keeping up I would think that you wouldn't be losing power.

KD,
I hate to admit that I have been researching this very topic over "there".
Here is a thread on how to use AE to check on the health of your HPOP.

I believe that you are correct in that the CEL will come on when the engine 'overboosts'.

Ward,
Maybe you can get someone to test your HPOP with AE before shelling out the cash for a new one.

KD,

Our OBS trucks wont set a CEL with overboost. And the light will go out each time the key is shut off for the P1211 code.

I posted a question about a scraping noise I'm hearing, thinking it was my turbo going to pot, but when I crawled on top of the engine today the noise was coming from the HPOP area. The turbo was purring quiet as a kitten. Guess I need a new HPOP, right?

for the scrapping noise-- make sure its not your belt, vacuum pump, alternator, or belt tension pully first....
as for the cel? dunno....
