Renault Megane RS265
The car was already equipped with full Akrapovic de-cat system, hybrid turbo upgrade, aftermarket intercooler, and had a generic tune by a UK company. The car produces 265 hp stock and previously mentioned upgrades have increased the power to 285 hp.
The car was custom tuned on the dyno; the result is healthy 332.5 hp, at the same boost level, keeping the stock wastegate.
