Max turbo psi?

I am looking for everyone's input here. I am looking at the Gearhead tunes and they are telling me that their tunes come standard with a max boost of 28-29psi. I feel that this is a little higher than the 24ish that I would prefer. I asked and they will send me one that has a lower threshold, but is this the right thing to do? What does everyone think? I would rather sacrifice a little power at higher RPMs and keep the turbo healthy.

Thanks in advance.

H&S canned tunes max boost at 24 to keep the turbos from blowing up, there earlier tuning was 30 and I think thats why we saw all the turbo failures. Atleast the failures have been alot less frequent, everyone seems to think the problems are just more prevelant on the 11-12 trucks and 13-14 are better off but nothing changed between 12 and 13 other then H&S tuning strategy. Sucks to say but the only way to find out if the turbos can handle gearhead tuning at 30 psi is to run it and see if we start having a bunch of turbo failures again. There was a thread just recently with someone that blew their turbo and I thing it turns out he never had his tuner updated and was running the old H&S tuning, he was deffinitely seeing 30psi of boost.

That is where I am now. My H&S canned tunes won't go above 22. I reeeaaaallllyyy don't want to blow a turbo. I just want the tranny tuning most of all. Is it possible to just load the Gearhead tranny tunes only? And have the H&S engine tunes?

I feel like 28-29 psi is fine as long as you don't sustain it for long periods of time, such as during towing. I don't have anything to back up my claim...

Yes, you can do that. I've tried it before, but it wasn't the same. I feel like the engine tune and trans tune were meant for each other...

Makes me want one of these again - http://www.dieselsite.com/19995-2003...ontroller.aspx

If it were only that simple.

Am I loosing anything by having them hold the max at 25 psi? Am I creating additional risk?

Less boost wont effect the truck much, lose a little power. But how often are you really in the powerband with WOT using every pony that tunes getting you anyways?

Still getting used to these low boost numbers on the 6.7's
My Spartan tuned 6.4 would hit 46 or 47 psi boost.
Think the most i've seen on my stock 6.7 so far is 21 or 22 psi.....feels like I'm towing a combine around all the time...but it does get decent mileage, slightly better than my 6.4....but it had 200 more hp too!

Just for curiosity sake what does a good aftermarket turbo cost to get installed in the 6.7 L ?

I have the Gearhead tunes. I've towed heavy up 6% grades and the boost hasn't gone above 25psi in his "stock" tune. I have my defuel set at 26psi.

I wouldn't run a tune that got near 30psi on stock turbo. For sure not towing.
