Pro Charger kit on the 6.2L Raptor has been awful , i have talked to many , many with issues. From blown motors to poor drive ability. Oh we had nothing to do with tuning any of them either..

Well, most folks are throwing down $45-55K+ to get into a 6.2 truck. They figure that if we can afford that then we can afford $6K for their SC. Hell, that's "only" a little over 10% of the price of a new fully loaded pickup these days.
Speed cost money. How fast do you want to go?

I wanna go fast! 
With no injectors nor tune, that's gonna cost even more, plus labor, etc.. This isn't looking as appealing, but I admit, I'm still interested...

It would be nicer if it was a turn key bolt on package like you can buy for a Mustang. Just bolt it on and send in your trucks computer while you are doing the install via overnight UPS or something. They flash it and send it back and you are only down for two or three days. We could be dealing with something we are not aware of though. Maybe the new trucks have the computer in a very bad spot to remove or maybe it has more than one module to program.
Now a days I don't see a need for removing the computor and sending it in like we had to in the past. (I haven't installed a SC system in about 8 years) I think it could be done by including an aftermarket programmer with the tune for your vehicle preloaded on it. If it has something to do with variables between vehicles they could still include a programmer. You could then send them your vehicles details and then download the tune and install it.

My issue here is that if you change anything like the headers, injectors, pulley, etc, then the stock Roush tune is no longer optimal. It is up to you to find a tuner like Mike to make the needed changes to the ECM specifications.

I've been thinking about this topic and the Squires Rear Turbo system came to mind. I believe they just finished a bolt-on kit for the 6.2L Raptor so they could probably produce a kit for our trucks with little effort. So what would be the advantage of this Roush S/C over this turbo...other than a little turbo lag and power available at lower RPMs.

With a 3-ton Raptor trying to fly over every hill it comes across or a 4.5 ton F350 designed to pull over 15K lbs and haul up to 7000 lbs I think instant power in the lower RPMs would be the main advantage. Who wants to wait for a turbo to spool up?

While I do agree with you on instant power, the diesel owners don't seem to complain too much

The 6.2L gas engine has 411 of torque at 5,500 rpm's... even with a supercharger, there is a significant lag time to reach peak power so any delay would be unacceptable.

I'll complain about it. We have had several oil burners (7.3, 6.0, 6.4, 6.7 and a couple of Dodges and Chevies) in our fleet at work over the years and I hate driving them. I can't tell you how many times I've been in traffic in town, stomped the go petal and was almost in an accident because it took so long for the turbo to spool and the truck to move. Yeah, given a few seconds they'll take off like a rocket or tip into the throttle on, say, a heavy pull up a long grade and the turbo will roll on the power. But I like my truck to go and go when I tell it too. I’ll never own a diesel or a turboed truck as my personal vehicle.
