This should definitely be of interest to Renaultsport Megane RS 250 Cup owners – 320 hp and 488 Nm running off the car compared to the stock 250 hp and 340 Nm should sound very much like a symphony to them ears.

Those are the numbers promised by a Stage 2 tuning package just introduced by UK-based performance specialist RS Tuning. The 320 hp at 5,500 rpm is dyno proven, and the maximum torque kicks in at just 3,250 rpm. Lots of tractability on call, what with over 350 Nm of the torque available from between 2,500–6,250 rpm.

It isn’t cheap, not at £2,499 (RM11,920) for the whole road legal (with sports cat) package, especially when you’ve also got to factor in shipping and taxes, but the outlay bags an alloy Forge Motorsport high flow intercooler, a choice of sports catalyst or cat bypass pipe (which cheapens things a bit), a Milltek stainless steel performance exhaust system and a specially developed RS Tuning ECU remap for the 250’s F4Rt engine.

There’s no timing data currently available for the RS Tuning RS 250 Stage 2 upgrade package, but the company says that road and track testing has revealed supercar style levels of in-gear and outright acceleration. For those who can afford it, the exercise should deliver an absolute stonker.
