Dinan's Stage 1 Performance Engine Software provides substantial power gains with a modest increase in boost. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage. Dinan's Stage 1 Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling. The top speed governor is removed, enabling the BMW to achieve its full potential. The software also features remapped water pump speeds as boost increases, better controlling operating temperatures which have been notably excessive even at stock boost pressures.
When BMW creates a software update so do we. Dinan will make software available at no charge to keep your car running as well as it possibly can.
- Max gain of 44 HP and 58 lb-ft of torque over stock
- Top Speed Governor Removed
- Full Map Rescaling
- Properly Returned Fuel Mixtures
- Remapped Water Pump Speeds to Control Engine Temperature
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.
