Dinan Stage 1 Performance Engine Software/Boost Upgrade Kit for BMW X6 xDrive35i E71 (DIY)


Dinan's Stage 1 Performance Engine Software provides substantial power gains with a modest increase in boost. Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, which includes 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, which enables 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 ordering please ensure you have your VIN ready for the checkout process. It is crucial that it is typed in accurately and completely at that time.

While we offer the DIY kits in the stage 1 form, the additional stages will need to be purchased and installed at an authorized dealer as they require hard parts to function properly.  

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.
