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

Benefits:

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.

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.

Drivability
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 and speed.
