Full review: http://www.autoexpress.co.uk/videos/featuresvideos/265933/superchips_renaultsport_mgane_video.html#ixzz1HbYQTomh<br /><br />Extra performance doesn't come cheap -- well not usually anyway. But for £445, Renaultsport Megane 250 owners can get their cars' computer reprogrammed by Superchips to boost power from 247bhp to around 300bhp.<br /> <br />So what is the effect on performance? To find out we raced a Superchips-tuned Mégane against the standard Renaultsport Mégane 250 over a standing quarter mile sprint. And then compared the two in a fourth-gear rollon from 50mph for good measure.
