Well Custom Import Arts finished today officially their stage1 tuning, with just a downpipe: 521HP en 775NM torque at the crank Still on 98RON. Now using the 'ron' as apparently there is a differene between the European 'octane' and the one used in US for example if not mistaken. Impressive numbers if I say it myself and look at that torque curve... lots of torque over the entire RPM range: Trying to pick her up tonight. Time for test driving. Unfortunately... it will be raining this week in Belgium.
