The strain a TT kit exherts on a motor is slightly different then the strain a SC puts on the exact same motor. For example a TT uses exhaust gases to spin up and power the turbo's ability to compress outside air. While a SC uses the front accessory drives and belt system to do the same job. That's the difference between SC and TT they strain different parts. Like what was said 8psi is 8psi and boost psi only gives us a tool to measure performance efficiency of a forced induction system...
