As an EP3 owner the physics seem somewhat off sorry.
Takes some serious effort to get that infamous lift off oversteer going, and when it does it's very gentle and controllable
vtec doesn't sound (or feel) like it's kicking in (yo!)
and not sure what mods they've bolted on to get that 230bhp number but the power graph looks like no ep3 ever, I mean 195Nm at 2000rpm?! A 230bhp with basic bolt on parts would struggle to get 170Nm peak (at around 6000rpm)
*edit - found the mandatory parts

so basically an uprated exhaust and manifold and a hondata ecu with a fixed tune
