Dinan Stage 3 Performance Engine Software/Boost Upgrade for BMW E89 Z4 sDrive35i

Product Description

Benefits:

98 More Horsepower / 129 More lb-ft of Torque 
Stage 3 Performance Engine Software safely increases turbo-boost pressure. 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 is a monumental increase over the stock 300 horsepower and 300 lb-ft of torque BMW quotes.

Tips:

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 agian.

First Spin
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.  

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.

Gas Mileage
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.

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.
