Dinan Stage 2 Performance Engine Software/Boost Upgrade for BMW E60 535i E89 Z4 (N54)

Product Description

The Dinan software actually increases water pump speeds as boost pressure increases. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.

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.

The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration producing maximum output of 378 horsepower at 5700 rpm and 415 lb-ft torque at 4300 rpm.
