i dont think so, but you might want to ask brayden himself

yeah the controller is not out yet. some 6.5 guys are looking at it because of the driveablity of the vgt provides and the mass airflow it provides for a 6.5 making 300 hp. brayden is taking his sweet time though.

last october he said it might be out by thanksgiving. 4.5 months later we got nothing. they do have a beta version though. one of his shop employees installed a bigger vgt on his truck that sizes up similar to a HX50 so they have a controller but have not released it yet for the public.

The Delphi actuator on all holset's 2007+ Ve models are the same, so the controller should work for 351 (HX40), 431 (HX50), 551 (HX55) and 561 (HX60) models.

The 341 (HX35) just uses a 12vdc motor and TPS, a monkey with half a brain could program for that. Older V models just have a 120psi air actuator on a lever.

I talked to holset themselves. I wanted to put a VGT off the 6.7 as my small turbo in a compound setup for my 5.9. He said it is a good idea but bad as far as trying to get the right electronics to run the vgt. He said the vgt turbos are ramped up for certain engines only and anything you do as far as performance adders affects the end results for the vgt turbo - usually not in a good way. Until someone makes an user adjustable vgt controller it is not worth it. Really I was dreaming of someday a dual compound vgt 1 Both the large and small turbo. But what a nightmare as far as ramp up times, speed, and duration. He said my idea could be valid, but for the backyard mechanic that does not have the millions of dollars of testing equipment - NOT WORTH IT! He said a set of compound like a hx40 - ht3b setup spools faster than a single hx35, lower egt's, more boost and horsepower. A win - win for multi-purpose trucks like most of us have.

Sounds like the guy you were talking to was either a parts swapping "technician" or a parts desk "technician". A VGT in a compound setup won't function any different than a wastegated turbo, it will just spool up a LOT faster. Replacing a wastegated turbo with a VGT is one of the single best upgrades for any diesel. I've done it to both my engines and both times its made a night and day difference in performance, even with stock fueling.

I seriously doubt anything with an hx40 can spool up "faster than a single hx35". Even the 6CT takes its time to spool that up.

James at RSD is right
Yes we are swapping the turbos for 5.9 turboes the other vgts where not a cost eff. way of making more power to me but I have heard rumors of some guys swapping them onto 5.9s ,but I would still guess you are going to have more $$$ in it than you would a good single fixed turbo anyhow just my .02. the stock vgt was to restrictive for my taste and my silver bullet spools just as quick on my truck as stock

Then put an HE431ve from an ISL in its place. All you would have to do is change the turbo map in the computer.

ok the 6.7l ecm is very hard to screw with though so still not really a good choice however on a 5.9 you would need a controller which in the end is going to cost more $$$$

You're willing to spend quite a chunk on a turbo, whats another $400 to have the best system?

Believe the whole point was to try to do it cheaply. Pick from A wrecker and just slap it in. So for the money not a better solution. And A straight swap of the 6.7 unit into the 5.9 is not A good cost effective up grade. To much trouble for truly no likely noticeable gain. Way better options that can be done cheaper then this route. Good luck.
