Dinan Stage 2 Performance Engine Software-Boost Upgrade Kit for BMW E70 X5 xDrive50i E71 X6 xDrive50i (DIY)

Special Note: Some 2013-2014 vehicles are not supported at this time. Please see your local Dinan Dealer for programming compatibility.

Software Description:

After many hours of further research, tuning and testing we have improved on our hugely popular Stage 1 Performance Software.  Our team was able to make Stage 2 much faster by improving turbo response across the power-band.  This tuning is especially noticeable in the first two gears, now catapulting the car off the line.  Tuned for a smooth power-band to put down predictable and even power in all gears and throttle positions.  This smoothness improves the quality of the shifting and the overall drivability.

With Dinan’s software, your BMW will be capable of achieving its natural top speed as the governor has been removed. 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.

Note: 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 (or stage 2 in this case), the additional stages will need to be purchased and installed at an authorized dealer as they require hard parts to function properly.
