We have swapped IDM's, computers, checked wiring from the idm to the injectors and tested out between .3 and .2 resistance, power going into the idm is the same as the batteries and does not drop when buzz tested. Injectors tested at 2.5 to 2.6 ohms. It is not just the tuner that made me notice this because it does it with the chip out. Right now both of are trucks are not tuned and his will still beat mine. Currently waiting for the chip to come back with more tuning changes to see if it makes a difference. It still does not make since that a truck with less mods is going faster then another with more. I didnt notice this problem till after the oil pump was installed.

So what are the problems being seen with these pumps?
What is it that Gary needs to get sorted out?

 

[mattman347]

Let us know how it works out with the tuning changes.

 

[woodduck97]

I will reply with the tuning changes and how the truck runs once I get the tunes and trans back in.

Also any thing that may be something to check let me know and I can try it.

No hot start and not making the presssure they should is the info I had. I do not think by any means that this was some huge widespread issue.

Fuel presure is good and stays good under WOT. Also have check the map sensor with and with out a boost fooler and unplugged it and noticed no difference.

Here is a video of it idleing last night after doing all the wire testing and stuff.

Here is a video back in april of what it used to do with the stock oil pump. Crappy video but can see the smoke it started to lay out after boosted up.

That sounds more like an injector issue then a pump issue from what I can hear in 10 seconds.

If you are convinced its the pump then swap pumps with your buddy.

Tom are you coming to Denton?

Guess last result will be that. Once we get chips back and see how they run.

 

[Tom S]

Tom are you coming to Denton?

That is the same weekend as our dyno day.

I hope Gary gets everything worked out great, he's a great guy, I've talked to him several times at local events and can't wait to get one of his pumps in my truck.

 

[Groomzybanshee]

so is stealth having a person problem or a problem with the pumps? or?

 

[Powerstroke Racer]

LOL I heard that rumor today as well.

 

[Tom S]

LOL I heard that rumor today as well.

Why so mysterious?

 

[Homesteader]

Just got clarification and the pump is just being put on hold but not discontinued.

Why is that? Problems?

premature failures and lock-ups i have heard about. Pumps completely seizing up.

 

[woodduck97]

Going to be till next week till I find out something. Been waiting on my transmisson from BTS for 3 weeks now since paid for.

Sorry for such the delay on what the fix was. Had a couple bad orings on the injectors. Guess the 15* pump was just not enough to blow oil by them. The truck still has a small bump in it but not sure what it is though.
