No, its not about turbos. Its about VVTi, which, like turbos, creates more power. Exact same truck, same engine BUT one produces more power. Its just clear who the winner will be.
you make it sound as if VVTI is some sort of turbo. it's not. it's hardly detectable. the diff between the v6 and v8 is way more noticeable. VVTI isn't even toyota's version of adding power. it's VVTLI.
look dude, there's nominal real life diff in real life between these two v8s.
sorry. that's just how it is.
