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.

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.

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.

Dinan® Intercooler Required: Stage 3 Performance Software is specifically built to take full advantage of the Dinan High Performance Intercooler with 93% more volume than stock all while reducing back pressure by 0.7 PSI.

Installation: Easy installation in about an hour at any of the +130 Dinan Dealers.  See "Authorized Dealers" tab to find your nearest dealer or contact Dinan to make an appointment.

Required Products: In order to qualify for Dinan's matching new car warranty coverage, which includes consequential damages, the vehicle must be equipped with the DINAN High Capacity Oil Cooler and High Performance Intercooler.

Shift Points: Dinan recommends up shifting at 6100 rpm as it is just above peak horsepower.  After the up shift the RPMs drop into the range of peak torque.  This is the "sweet spot" as it keeps the engine constantly moving from peak torque to peak horsepower and back again.

Break-in: Dinan Performance Software can be installed at any time over a vehicles life.  If it is installed by the dealer at delivery Dinan suggests to strictly adhere to the BMW break in procedure.

Performance Software Stages & Upgrades: Any stage can be installed at any time and, if upgrading, just pay the price difference between the stage you currently have and the stage you are upgrading to.

Free Flow Stainless Exhaust (D660-0043 & D660-0043-BLK): An important addition for any enthusiast who wishes their car to sound as good as it performs while also supplying significant power gains itself. These exhausts are dyno tested for maximum exhaust flow with minimum backpressure. The system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to Dinan’s exclusive Helmholtz Chamber and Butterfly Valve technologies.

High Flow Carbon Fiber Cold Air Intake (D760-0034):  Our cold air intake force feeds the 3 liter turbocharged inline 6 with greater volumes of cool, oxygen rich air for substantial power gains by utilizing our secondary carbon fiber intake. The system is so effective that the carbon fiber inlet air temperature is a full 40 degrees Fahrenheit cooler than the incoming air from the stock inlet. Due to the increased airflow from our intake, the power-curve is extended into the higher RPM’s for a noticeable change. The system is a direct replacement for the factory air box lid, employing a hand-crafted carbon fiber unit that also includes a secondary carbon fiber intake tube that captures cool air from the lower grill and includes the shielding for the conical filter to insulate it from power robbing engine compartment heat.

High Performance Intercooler (D330-0010B): Greater power gains are achieved with a larger high performance intercooler. The Dinan® intercooler offers double the volume of the stock unit, substantially reducing the pressure drop by 0.7 psi, as well as providing more efficient heat exchange. "Cool down" time is also reduced, enabling the cars to produce full power under varying driving conditions such as stop and go traffic. The system has been engineered as a direct replacement for the stock unit, requiring only minor modifications for a clean, factory-like installation. The intercooler also features larger connector tubing and custom shrouding for maximum efficiency.

High Capacity Oil Cooler System (D570-0822): BMW 1M comes from the factory with an auxiliary radiator smaller than a half sheet of paper. It will do little to keep the "limp mode" or heat soak away during a track day. The Dinan High Capacity Oil Cooler provides literally twice the volume of the stock unit, as well as 414 sq./in. of cooling tube vs. 112.5, and that's really just the beginning. Nicely integrated inlet ducting provides greater airflow efficiencies and the ventilation of air to the fender well has also been improved with a larger outlet.
