Product Description

The Dinan Engineering Team made a blistering fast software upgrade that will push your guts into your spine, smoke the tires and put a big smile on your face.  Using years of experience tuning BMWs for the street as well as winning back-to-back Grand-AM DP Championships and the 2011 24 Hours of Daytona the Dinan team is the best in the business.

Dinan Performance Software is so much more than just tuning up the turbo boost.  It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place.  Protecting your BMW while giving the most performance is the definition of "Performance Without Sacrifice".  Drivetrain and engine components are analyzed for strength then the program is tested on the dyno and in the real world for durability and drivability.  Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages.  The top speed governor is removed on RWD vehicles, enabling the BMW to achieve its full potential. 
*The stock top speed governor is retained for automatic transmission vehicles.

DINAN Performance Software FAQ:

MPG with Performance Software on a turbo car?:
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 higher boost levels that more fuel is used.  It all depends on your right foot, if you drive gently the car will use the same or slightly more gas than stock and if you drive it at wide open it will use more.

I do not live near a Dinan Dealer can I still purchase Performance Software?
Yes, for most cars the engine control computer (DME) can be removed and shipped to Dinan HQ in California for reprogramming.  Most DMEs are received, reprogrammed and shipped back out within 24 hours. For questions or to order please call 1.800.341.5480.

Will Dinan parts be covered under my extended/CPO warranty through BMW?
The Dinan warranty matches the new car 4 year / 50,000 mi warranty and does not cover any extended or CPO warranties.  Read the full warranty here: http://www.dinancars.com/warranty.aspx

Will the chip hurt my engine?
Yes and no… We work very hard engineering our products to work within the limits of the engine components. If we know we are asking too much from them, like with the Stage 3 software we require improved cooling with the Dinan oil cooler or intercooler to keep everything within the limits.  On the other side, nothing is free and we are asking the engine to do more work and that will increase wear.  Dinan backs its software with a BMW factory matching 4 year/ 50,000 mile warranty.  We are as confident about our products as BMW does about theirs.

Will stock parts hold up to the added power gained from Performance Software?:
Yes, part of our R&D process is scrutinizing every component for the ability to handle the extra power added to the system.  We must do this because of our BMW factory matching 4 year/ 50,000 mile warranty.  We feel as confident about our products as BMW does about theirs.

Do I need to install the Performance Software stages in order?
No, any stage can be installed at any time if additional required parts are already installed.

If I upgrade to the next stage software do I have to pay full price?
No, just the price difference between the stage you currently have and the stage you are upgrading to.

After installing Dinan Performance Software who can service my BMW?
