The boost is tapered at the higher levels to keep from overheating and damaging the turbos. With a peak horsepower of 398 at 5700 rpm and the peak torque of 429 lb-ft at 4300 rpm as tested with Dinan High Capacity Oil Cooler System and Dinan Free Flow Exhaust is a monumental increase over the stock 300 horsepower and 300 lb-ft of torque BMW quotes. Power: Being only 1 lb-ft and 14 hp short of a stock M3 in a package that costs less to buy. fill with gas and insure it is the perfect weekday commuter and weekend canyon carver. Drivability: There is more to a tune than just cranking up the boost. Power needs to come on smoothly and in a predictable way to make the car as fun to drive at wide open throttle as cruising around town. It is your BMW. but reborn with new found acceleration and speed. Top Speed Governor Removed: Dinan’s software removes the top speed governor so your BMW will be capable of achieving its true natural top speed. A True Software Tune: The biggest difference between a true software tune like Dinan's Performance Software and a "piggyback box" is that all of the communications between the engine sensors and the engine management computer (DME) remain unaltered. This translates to properly returned fuel mixtures. Ignition timing and full map rescaling to keep everything in sync. Keeping an engine running at its best and with the most reliable power is what Dinan is all about. Well Engineered: Properly returned fuel mixtures to the DME along with a correct tune means keeping the engine running cooler with less wasted fuel. Ignition timing is a critical part of the equation to limit engine knock. one that many tuning companies ignore. Dinan Performance Software includes full map rescaling to protect the engine and keep everything running smoothly. All BMW Engine Safeguards Retained: BMW worked hard to build systems to protect the engine incase of a failure. Dinan keeps all of these systems in place for the safest possible tune. Remapped Water Pump Speeds To Control Engine Temperatures: The N54 engine is known to run a little warm in stock form. In an effort to more effectively control oil and water temperatures. the Dinan software actually increases water pump speeds as boost pressure increases. Easy To Use: Add modifications and use different levels of octane without worry because the ECU will adapt to the changes. automatically leaving you to just enjoy your Dinan tuned BMW. ; Gas Mileage: This is the beauty of a turbo engine. When the engine is not in boost (below about 3K rpm) it is sipping gas like a small non-turbo engine would. It is only in boost that extra fuel is burned and with the Dinan software more is burned at the higher boost levels. It all depends on your right foot. if you drive it gently it will use the same or slightly more gas and if you drive it at wide open it will use more.
