Your boost threshold may be 3600 rpm, but there's a delay between pressing the throttle and the time the turbo spins up. On a WOT run, it's less noticable than transitional on/off throttle situations. A turbo setup will never have the same throttle response as a SC since you're driving the SC directly off the crank pulley. It's a trade-off. SC's are going to have better throttle response while making full boost closer to redline and producing less torque. Turbos just have more steps in the process to making boost, and it shows up as lag. I'm not going to touch the Stillen vs GTM SC issue.
