I think you're right.  Here's just a few of my concerns though.  Price.  That's a lot of money for 130hp and 110tq to the rear wheels.  That's obviously a big bump but if you are wanting the numbers they are claiming you will need a smaller pulley on the S/C for more boost.  My other biggest concern is fuel management and have they been able to dial it in to where you don't have to worry about melting the pistons down.  I have no reason to not believe the base engine can't handle it, I'm sure it will handle the boost just fine as long as it's getting enough fuel.  So to wrap up my thoughts, fuel requirements, curves, open loop closed loop.  It will work just fine as long as they have their fuel mapping down to a science.  I look forward to seeing the actual real world results and would never sign up to be a test case for this project.  But it is cool as hell.

it is a nice option to have any way. what i also wonder is since my truck is ordered with the flex fuel option how that plays into it. its cheap race fuel but uses alot more of it. ive always been a procharger guy, but in my opinion that new whipple 3.0 liter blower set up would make more sense for a big heavy truck that needs the tourq more than RPM. look at the challenger/charger hellcats theres a reason those are pd style blowers on em cause there heavy pigs. but dont get me wrong a procharger can work on a heavy vehicle but  it usually needs 4.88 gears and a 3600+ stall converter and plenty of RPM to get it in its power band. id go the whipple route my self.

I have driven a PC'd 6.6 truck and its night and day the difference.  As far as the "downlow TQ" comment, you can look on both Whipples website, and ProChargers blog and both posted dyno sheets.   The PC is making monster TQ and holds it all the way out to 5100+ rpm.  

Whipple DYNO LINK (under attachments tab) 
ProCharger DYNO LINK (lower down) 

With the new 10 speed trans, there's virtually no more reason for a "high stall" converter.  Long gone are those days of the 4L80's and wishing it had more gears.  As far as price, sure wish it was cheaper (but then again I wish the truck was cheaper lol)... guess its about like the uptick to the diesel,... but still retaining the "simplicity" of the gasser.

ive put together 3 procharger set ups first was a built 4.8 and 4l60 second was a built 5.3 and 4l60 third was a built ls1 / 6spd stick. and a stall definately put it in its power band i could see more gears in the tranny helping alot but both kits are for 2020 to 2023 trucks and are 6pd only so no 10spd as of now. and i will say a procharger has a linear power curve more rpm more impeller speed with a 4 or 5 to one ratio gear box that spins it, ive had a p1sc1 , p1x, and a d1x (i belive i was spinning that p1sc1 to around 61,000k impeller rpm) and all were amazing but not low end monsters thats where gears and stall comment came from. and no i wouldnt do that to a hd truck with 6gears and 3:73s already from the factory. i have also driven a tvs 2650 on a gm truck and a whipple 5.3 truck, and both were instant tire shredding power right off the line. cause they are positive displacement style blowers and not centrifical blowers. the procharger dyno shown above started at 4,200rpm and the whipple dyno started at sub 3,000rpm, plus we all know two different trucks on two different dynos really doesnt show anything that is actually comparable  any way. id love to have a actual side by side comparison of the two, (as in both trucks same place same day)  and im betting the whipple truck would have more low end and the pc truck would have more top end just because thats the nature of those types of superchargers, remember a procharger is basically a belt driven turbo and a pd style blower almost mimicks more cubic inches as in more air flow at low rpm but runs out of steam up top. im not nocking on either i think they just have different qualitys is all. id be proud to have either under the hood of my 6.6 gasser.

I don’t think the 24+ trucks will ever be able to be modded like this due to Theo extreme lock down from big brother GM corporation. Is it true they can unmod the vehicle over the air or some such sorcery?

thats what ive heard,they can do all updates/and pretty much spy on you any time they want. im glad i got a 21 with the 6spd heck mine didnt evan come with on star, i did add the flex/e85 option though . most guys dont believe me when i tell em that but if you ordered up a w/t truck and just add everything you wanted it was the way to go (at least for me). i think in the future people will really want the 2020 to 2023 trucks cause they can be modified easier. thats not to say someone wont figure out a work around for the 2024+ trucks eventually.
