That's what I've learned it to be referred as.Not interested in smoke,But wanting to learn more about the options and what they benefit for when they were used.
I will never help anyone disable their vgt system on any diesel, not even so much because I care that you want to roll coal (you are going to find a way anyway...) but more so because I don't want to deal with you when you start b1tching about cracking or melting a piston... Or wondering why your turbo is sticking...
I care more about the diesel motor under the hood of your truck than I do about you... If you want a cool truck spend the money and do it right, if its going to smoke make it be because you have 800+hp under the hood... Not because you want your friends at school and on face book to think your truck is cool.
And if you want to do it right its going to be in the tuning, and the only way you are going to get a tuner to do it is at idle... Once you step on the noise pedal the vgt system will re-engage.
That's what I was wanting to get more of a answer for.Not any bashing,Thanks.Does it help mpg?I have the single turbo kit from H&S.Never really cared to learn about what this switch was about.But I was wondering if it was a good rout for people who have done it.Or just a waste of time.
Personally, for drivability the VGT system is worth its weight in gold... Combined with the compound setup that our trucks have it makes for amazing power off the line (and very smoke free/low egts). Unfortunately it also means much higher back pressure and limited turbo performance up high. For a DD/tow pig you can't beat our turbo setup.
For competition a big single really does shine (still to a point...) just because of the sheer amount of air it can pull. But a single kills the ease of driving that our trucks have. And fuel economy has more to do with the design of the 6.4 itself. Our trucks power bands generally sit higher than say a cummins, that means there is more fuel to get moving but once you are moving they have more power left over. Our trucks don't do too bad once in lockup on the freeway mpg wise... Its just getting the truck moving that is the problem.
As for longevity, any turbo upgrade is really going to require studs to get full use of it. And at that point you are risking your pistons anyway... The real weak point in a 6.4 lies in the pistons and camshaft design. And until they are addressed it doesn't really matter what turbo you have, there is always that cylinder pressure battle again the pistons.
As for disabling the vgt system itself the ONLY advantage is noise... It gets rid of the angry hairdryer noise that our trucks are famous for........ You will sacrifice performance and everything else...

I understand,What if I would've taken the rout of downloading a max calibration control.And adjusting the turbo to kick in at certain rpms.So I would've had that good sounding idle.Would I have problems down the road.Even tho the turbo will still be running and not just sitting.Only after certain rpms of course.
I'm interested in possibly doing an h@s single turbo but have been reading on other turbos and cheaper routes I've tried finding a way to put a new post but can't find how to do? Any help would be appreciated.
Browser. I'm looking into that also. I have alot of research to do and why I wanted to post on this forum the guys on here know what to do and are very smart
