Those will all give you instant torque and throttle response. Good luck whatever you choose.

I hear ya man, to be honest, I've gone back and forth on this issue now for a little over a year.. I've weighed the supercharger vs. turbo debate for what I want to do with the truck.. I'll be honest, around here they run some pretty wide open courses. If I was still running in a region that ran mostly parking lots then I'd tend to agree with you. The reality is, most of the regions here run on old airport ramps with a LOOOT of area. Tuning is key with a turbo, and these days the technology incorporated in the turbo is lightyears ahead of what it used to be.. With a 4.8L and a properly sized turbo boost can be had at 2000-2500 rpm range, add a 2800 rpm stall and its all good. In all honesty the only place I probably wont see boost is off the line and I can foot brake that.. I've owned supercharged and turbocharged cars in the past and I feel the best balance is with the turbocharger.. Eventually I plan on going with a semi-built 6L to replace the 4.8, so light off will be even better..
Anyhow, I do appreciate the feedback, its been perhaps the biggest argument I've been wrestling with on this whole project.
