Gauges installed... Now questions-UPDATED

See Page 2


So I got the Isspro 2's installed today and they are sweet. But...

1. Boost- I'm getting almost none till 2500rpm and from then on not even hitting 10psi. I'm thinking it may be time for a turbo rebuild. It would also give me an excuse to go with the WW2. It ties into the map line with the supplied stuff.



2. Fuel Pressure- It bounces around between 10-20 on idle and makes just under 25 in normal driving. Ideas? I'll post a vid tonight. I had a fuel leak which I fixed by replacing the dashboard sensor sending unit a month ago(silver one on the left). That is where the T is, one side for the dash, the other for my gauge.



3. Pyro- Nothing wrong here! It works great.

4. Glow plug LED- I was surprised to see how long they stayed on after the truck was running.



It makes me laugh that my truck has basically no boost and here I thought that I had alot, cause you can hear it! So with 207k miles on it I'm just starting to get to know it well. Beans Chip will be ordered on Monday...

Gauges installed... Now questions

Get a mechanical boost gauge. When I had my edge with the screen it said I was only running like 10 psi too. And It would take for ever to get there. I have my line right in the manifold now and I have the proper readings.

i don't know about the boost, but it doesn't sound right.

fuel pressure is low because the fuel pump is dying. need a new one.

I figured I needed a new fuel pump. now to decide between efuel and the mechanical pump...

Boost is only on acceleration. I took it for another 15 mile test run. Pulling a steep hill in 3rd I hit 15psi of boost. Sounds about right to me for 207k miles.

Can I expect more boost with a tuner than I get now? I'm trying to squeeze every mpg out of my truck while staying with 4.10 gears.


Thanks for the help, Nate

You will get a lot more boost with custom tunes, and all my gauges are mechanical aside from the hpop, I can get 32+ psi easy

I have the same gauges and I tapped the sensor into the intake y with great results. Just a thought.

I'm going to leave it where it is for now. Next weekend I will tackle the fuel pump, fuel lines, Y pipe boots, T stat, hoses, and coolant...

Should/will I have to pull the turbo to get the fuel pump out? I'm ok with that, just wondering how big this project is going to be.

no you don't need to pull your turbo to change the fuel pump
