Boost referencing is not the total answer. The better the cam, the more porting on the head, and how much air the turbos will move, would really make the truck touchy. Picture holding the throttle steady, and then as the boost built the truck kept picking up speed.
I have daily driven my 05 using the TNT/R for the last couple of years. About the most I usually change on it, is the shift defuel, because Patty likes the comfort of knowing what gear she is in when she drives it. Then again sometimes I leave the shift defuel on when I race if the traction is limited.
I'm running the SSR now, and yes the driveability is improved. The low level settings allow me to adjust the fuel settings to how my engine breaths. I can also make it as responsive to throttle input as I like. The high level settings just plain make hp. I'm very impressed with those gains.
End result though is, that you have a couple of inches of pedal movement to go from (in my case) 0-1000 hp. With the SSR I can adjust how I want that pedal movement to control the hp. I can have it do it in a linear fasion, or be soft on the bottom, and then come on strong at the top. With the converter, cam, head work, and turbos I have, I'm almost always a second or so away from exceeding what the stock map sensor will read.
