New Turbo and still NO boost. HELP!!!

Your stock boost sensor will not read high enough. You need an aftermarket gauge to read higher than 24psi.
Not to hijack the thread or anything, but when you suspect a boost leak, or youre not making enough boost. At what point will a code be thrown? Or will there even be one
Most tuned trucks won't throw one.. Especially if they have a turbo change..
I think anyways

Gotcha. Just curious. Id imagine he would have one, but i guess not if his is tuned by rob. Mine is Rob tuned as well, only code ive ever got was a overboost code
Not sure how Rob does his tuning so im just guessing. I had an lbz that I bolted a 3794 on and went and drove it, jt threw an underboost code at some point while on the drive. Tuned it and now it's gone.

Danville turbo said my up pipe gaskets may be in wrong. Guess what I'm doing when it cools down today. Joy.
Have you logged rail pressure? Mine was a dog when the fprv went bad and then when the injectors were bad it was laggy.
I had Texas Diesel Power in Weatherford look at it again today. Had two techs drive it and did a fuel pressure test and about an hour on the Tech 2 scanner.
Have they read or logged all your major sensors? Sounds like a sensor or fuel issue to me, but with out a actual boost guage a boost leak you can't tell unless you do a test.
Soooo when do you drive it to Josh & get a real diagnosis? Not to dog that shop but they spent an hour with it & didn't come up with anything?
What's ur maf reading at? Check mouth piece. Up pipes. Boost tubes intercooler pipes. All that good stuff. A data log to a good tuner such as rob or mark will tell alot. Air flow vane percentage the list goes on but good luck!
I sent you my phone number in a private message. Text me when you get a chance and we can make a date to pressure test and hook up my laptop to it.
I've cleaned my MAF a few times now. Crawled all over, under and inside the engine compartment. Spraying carb cleaner on the boost tubes and fittings to try and find a leak. Changed out a fuel filter with 2k miles on it, then changed out the fuel filter housing. I don't have any codes.
What are you using to scan the ECM for codes.?
