My mildly tuned Eric's I.Diesel tuning. will hit 21 - 22 but nothing more.

Is this a sign of coking and carbon or normal?

Any advice is appreciated.

Average? I run betweel 0-2 on surface roads and 0-8 on the freeway.

I can hit 26psi on flat ground unloaded if I try.
Its easier when on a hill or loaded.

 

Early 99 with original wicked wheel was getting 17 psi max. Now with new compressor wheel I have seen 19 psi.

 

So is the normal operating range in the low 20's for an 05 6.0 w/120K on the clock?

Does programming play a part in how much boost is generated?

I could PEg my 30psi gauge on my 2000. TS chip,stacks & CAI. Problem was when towing I would get SEROUS surge and had to let out of it

 

Moved to the 6.0L Power Stroke Diesel forum.

 

an 03 compressor wheell doesnt have as many fins, and doesnt move as much air. an 05 should be able to get over 20psi easily. i coud get mine to push 25+ stock.u have some problem swith ur vgt or actuator, but im not sure what.

 

What are you reading boost with?

 

dash gauge

 

Are you seeing those numbers in the stock tune also? I'm pretty sure that reading is going to be inaccurate when you have a tune installed.

 

I don't know, why would I run the stock tune, other than to test this.
I vaguely remember it never going past 20.

 

My stock 2003 will hit 27-28 as measured on my Isspro boost gauge.

 

26 to 28 should be the safe max on any stock 6.0. Flat level ground on the highway at 70 I will run about 5 psi. Punch it and I get about 22. Put the fifth wheel on it and I approach the 26 to 28 mark. The gauges are kind of iffy in this range. Refering to the marks and lack of numbers in this area of the gauge.

 

Stock tuning the highest I've seen is 27 or 28.

 

bone stock with my 04 6.0 I can run 24 to 26psi. with my quadzilla turned up to 65hp the towing level I can hit 27 to 29psi. Nothing ever over 29 I have seen.
