If I have leak on my up pipes, then somehow there has been zero residual diesel soot left behind. And as I told Jody, I pressure tested my system at 15-20 psi, soaked all the boots and even a good part of the inter cooler with a water detergent mix and found no leaks. The truck is strong off the line, but has minimal top end. When I had my last SD with a Western diesel chip and stock turbo, and injectors with a 4 inch exhaust, I consistently made 28-30 psi at this altitude. In fact, the boost numbers were the same when I went to sea level, it just got there a lot quicker. I had my tunes altered by Jody a month after I got my F8 chip. I think that was a mistake and now, in spite of repeated requests to go back to his original tunes, I am stuck. It's all about my truck, or my turbo, or I have leaks. I am a business owner and I have to say that as such, I am very let down my the customer service I have gotten from DP Tuner. I know others have had outstanding service, I have not had the same experience. When I can get in the truck in my shop, I will re-test, but I have not found a boost leak in the previous two attempts. EBPV is out too, pipe is clean and sensor is clean.
The question is: whats your fuel mileage like with that setup. Thats crazy boost there.Gt42r, DP Tuned, 250/200 Industrial Injection injectors...Pegs a 60lb. boost gauge
He has already fixed his fuel pressure and is where it should be.Frustrating situation. I'm wondering if it could be a fuel pressure issue? Or possibly a defuel from the chip/pcm?

As far as defuel, I do not believe that would happen without codes or ses light. I know the DP chips do not defuel and there is no limit on boost. I called and asked a couple days ago. They still think some kind of leak somewhere. I say this because I am in a similar situation as SD.
This is the same as me, but I do not think I have excessive play in the impeller shaft (although I have never checked a new turbo either).I would get 25 psi with the mods in my sig when on the 80E setting. That being said, i'm only making 20 now since the turbo shaft has play in it. I'll let you guys know what i get one i get my new turbo and install it.
I decided to go with a setup from Irate Diesel. Its a modified S300 that is done by Pius at Bell turbo. It was down to either the GQSSB of this turbo, and after doing quite a bit of research i decided to pull the trigger on this one. I'll let you guys know how things go once i get it and get it installed.This is the same as me, but I do not think I have excessive play in the impeller shaft (although I have never checked a new turbo either).
Will be interesting to see what you results are. Did you ever decide on a turbo?
