RENNtech Tuning usually deal with ECU tunings and exhaust system fiddling. Now the Mini Cooper has been introduced to them and it wont be an exception.

ECU upgrades will be available for both Mark 1 (2006-2010) and 2 (2010-present). The RENNtech people have an already developed tuning program for BMW so why not MINI? Significant change after the upgrade, can be felt in the "S" and John Cooper Works editions. By modifying the ignition timing and throttle mapping, optimizing air/fuel ratio, overriding the top speed limiter and tinkering with the turbo where possible, RENNtech's ECU upgrade has managed to extract 45 hp more from the standard engine. On Mark 2 MINI that ECU boost can be initiated by the press of a button (the sport button) so that the driver can have full control on the engine works.

To round things up, RENNtech have thrown in an Akrapovic Evolution Exhaust system and an optional down pipe for the additional 8 hp and 10 lb/ft of torque. Who says toy dogs can't bite?
