The Dinan flash tuning catalog continues to expand with the BMW 'F' Chassis N55 calibrations (non-M2 / PWG) being the newest member. With gains of up to +95 WHP / +120 WTQ on an otherwise stock engine along with a removed top speed governor and multiple octane calibrations, a new level of enjoyment is a dealer visit away. Even those with DINANTRONICS ELITE's can switch over at no additional cost should you not want to miss out.
