The 950hp twinned on both trucks was with the BMW 65mm.
The vanes are just a different design to give more flexibility on high horsepower setups and twins, Hopefully Mark can chime in and answer on the wheel upgrade I'm not sure about that part .
You can it's been done you'll just have to use fleece performance turbo brake controller if they still offer it or you could find a used one search vgt lb7 on YouTube unless the vid has been removed I'll see if I can locate it and post if i can figure out how to on this iPad
Yes, Chris is exactly right on this. The wheel upgrade basically turns this turbo into my old DP Billet68mm Stg2 for a cheaper price since I am not having to machine a stock cover to fit this wheel. My new turbo will be taking the place of my old 68mm stg2 but will be called the Stg2R because of the upgrades. The high flow vanes are more for top end setups that need a little more tuneability out of the vanes themselves. Not something that 90% of the guys out there actually need. Hope that helps guys!
It was 29°F this morning and it was the first time the truck has gone into high idle since the install.

Ok.LBZ-I'd do the 68mm Stg2R in that situation for best performance and drivability!
Ended up sticking with the 3794. Will see how she does twinned with the S480.
