Dinan Stage 1 Performance Engine Software/Boost Upgrade for BMW E60 535i E89 Z4 (N54)

Dinan D900-30TB-1


The top speed governor is removed, which enables the BMW to achieve its full potential. The software also features remapped water pump speeds as boost increases, better controlling operating temperatures which have been notably excessive even at stock boost pressures.

Dinan's Stage 1 Performance Engine Software provides substantial power gains with a modest increase in boost. 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. Dinan's Stage 1 Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling.

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.

  • Max gain of 44 HP and 58 lb-ft of torque over stock
  • Top Speed Governor Removed
  • Factory Matching Warranty (4year/50,000 mi)
  • Full Map Rescaling
