Dinan flash tuning is officially back! Kicking off this new era are the BMW S55 calibrations. With gains of up to +146 WHP / +155 WTQ, a removed top speed governor, multiple octane calibrations (for some variants) and options for a factory matching warranty, there is a solution for nearly every S55 owner. Even those with DINANTRONICS can switch over for minimal, if any, cost should the desire arise.
