Special Product Notes
The Dinan High Capacity Oil Cooler and High Performance Intercooler is required for Stage 3.
98 More Horsepower / 129
More lb-ft of Torque
Stage 3 Performance Engine Software safely increases turbo-boost
pressure and is optimized to take full advantage of the High
Performance Intercooler. The boost is tapered at the higher
levels to keep from over heating and damaging the turbos.
With a peak horsepower of 398 at 5700 rpm and the peak torque of 429
lb-ft at 4300 rpm as tested with Dinan High Capacity Oil Cooler System
and Dinan Free Flow Exhaust is a monumental increase over the stock 300
horsepower and 300 lb-ft of torque BMW quotes.
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.
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
BMW Factory Matching
Warranty (4year/50,000 mi)
No one offers better performance or backs it up with such a
comprehensive warranty coverage. Dinan matches the new car
warranty coverage for up to 4 years or 50,000 miles, including the
possibility of consequential damages. If your BMW is past the
new car warranty Dinan parts are covered for 2 years and unlimited
miles. See the Warranty tab for full details.
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.
A True Software Tune
The biggest difference between a true software tune like Dinan's
Performance Software and a "piggyback box" is that all of the
communications between the engine sensors and the engine management
computer (DME) remain unaltered. This translates to properly
returned fuel mixtures, Ignition timing and full map rescaling to keep
everything in sync. Keeping an engine running at its best and
with the most reliable power is what Dinan is all about.
Properly returned fuel mixtures to the DME along with a correct tune
means keeping the engine running cooler with less wasted
fuel. Ignition timing is a critical part of the equation to
limit engine knock, one that many tuning companies ignore, Dinan
Performance Software includes full map rescaling to protect the engine
and keep everything running smoothly.
All BMW Engine Safeguards
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
Remapped Water Pump
Speeds To Control Engine Temperatures
The N54 engine is known to run a little warm in stock form.
In an effort to more effectively control oil and water temperatures,
the Dinan software actually increases water pump speeds as boost

Updates For The Life Of The Car
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 (dealer installation charges may apply).
Dinan Oil-Cooler Required
Due to the warm tendencies of the N54 engine and the added performance,
the Dinan High Capacity Oil Cooler System is required to keep the
engine within BMW temperature tolerances.
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.

Easy To Use
Don't worry about cutting wires, downloading maps for different octane
levels or uninstalling before service. Just install and you
are done! Add modifications and use different levels of
octane without worry because the ECU will adapt to the changes,
automatically leaving you to just enjoy your Dinan tuned BMW.
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.
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
After software is installed the engine management computer (DME) needs
to adapt to the new programing and takes about 100 miles to
complete. Over the 100 miles the car will become faster and
more responsive and so will your heartbeat.
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.
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 boost that extra fuel is burned
and with the Dinan software more is burned at the higher boost
levels. It all depends on your right foot, if you drive it
gently it will use the same or slightly more gas and if you drive it at
wide open it will use more.
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.
