Without causing a big todo, I'll say.....I disagree about power levels on the TVS vs Gen V with heads, IC etc. Been there, done that...following in the footsteps of a car that made equal your current power level. That was 93 octane, no Ethanol to suppress knock. Yes, a lot more parts, but done before the TVS was an option.
BTW guys doing cost. Don't forget TB adapter, wiring, maf change etc. Although no matter how you look at it.. the TVS is good power for the relative money invested without any "credit" for parts replaced. The cooler we can get a supercharger output temps....the better off.
