If this was for Stinky, I would... but I'm **** about Servicing Stinky (big A.S.S. on my shirt). Now I'm wondering what prompted an HPOP replacement. Don't get me wrong... my T500 really helped at 250K with the tunes on stock sticks, and it does an amazing job with the Stage IIs. I'm just curious about how this all came about... what with a bad ICP and all.

Dont think the icp was bad till after I did the hpop. Did some data logging a few months ago. Think I emailed you the files. But on 80e WOT icp was only getting to 2100 or so and iprdc was 100%. Then on stoxk was about 2800 and 65%. Had several people recommend a new hpop. Had a little $ saved up so I got one. Then when I tore into it realized my ebpv was leaking along with my up pipes. So I fixed it all.
Think my icp went bad when one of the hpop lines popped off and sprayed oil everywhere

Also my pw was 5.5 - 6 ms at wot. Everyone said my egt's would be high so got the egt probe for my infinity and on 60e wot at about 75mph got to 1200 cruising at 55 was 750.
We will be using the truck hauling horses to trail rides and my daughters rodeos and 4H. So I want it in top shape, especially when I cant go and my wife and daughter are on their own

Correct, If you see oil on the plug it is time to replace it. Oil will start to seep throught the sensor when it is starting to fail.

ICP is (looking at the top of the engine) on the front drivers side oil rail. Right next to the engine hoisting eye. The IPR is in back side (valley of engine block) of your HPOP.

Yeah been waiting on DP to get that Cie hub released and i'm gonna add the fuel pressure guage among others. Is there any way to tell if the hutch mod has been done by PO? i think the harpoon mod may have been done because when I fill up there is no toping it off, diesel is right up to the top of the neck.

I wonder if my ICP was going and the new HPOP finished taking it out? when I first started the truck it ran good, let it idle for about 10 min then went for a drive, about a mile from the house it died. Took about 15 min to get started then ran really rough till I unpluged the ICP the next day.
Thanks Rich for reminding me to unplug it to see what it would do, or I might still be out there cussing it

Ok, got my ICP sensor in, pretty sure that was the problem. Running great now.
Can't tell how much the HPX and FRX helped because I installed a T500 at the same time, but WOW there is a differance. Think it's a little quiter but I only got about 25 - 30 miles on since I got it back together Much better throtle response, even at WOT in 80e my PW toped out at just a hair over 5ms. My EGT about 1150, and IPRDC about 75%. Much better than it was. Also crusing at 60 my EGT runs about 500, it was at 750.
My SES light went out when I put the new ICP on but under heavy throtle it comes on for a few min, but I think that is the overboost thing, but it didn't do that before. Pulled my codes and had 6 different ones but I didn't clear them before I went for a drive, so I cleared them and we'll see next time I go for a drive. Overall I'm very happy

So I looked today and there is a steel line coming from behind the tank in the frame rail then goes to rubber line then a quick disconnect where the rubber line attaches to the pump. So it has not been done, correct?

I don't know if the in-tank mods were done, but it's not a full Hutch mod.
- If you have 60e, experiment with that and 80E while recording data.
- Replacing the QDs with diesel injector hose (not cheap) injectore hose clamps (different design than what you're used to), and an inline diesel screen-type filter... PLUS doing the in-tank mods will finish off the air-in-fuel issues. Your engine will run a little quieter and it will likely help the whole ICP/IPR/FIPW thing.
- Repeat step 1.
