I just got an email from Dinan, thay have finally released the remap of the engines in the s35i . I can't stop smiling for some unknown reason... 
Stage one is an extra 66hp etc.
This is an exerpt from their website:
STAGE 2 PERFORMANCE ENGINE SOFTWARE/BOOST UPGRADE (Oil Cooler Required)
78 More Horsepower
116 More lb-ft of Torque
Top Speed Governor Removed
Factory Matching Warranty (4year/50,000 mi)
Properly Returned Fuel Mixtures
Remapped Water Pump Speeds to control engine temp
Free Dinan Software Updates for the life of the car
Oil-Cooler Required
Dinan Stage 2 Performance Engine Software for the BMW Z4 safely increases turbo-boost pressure, adding 78 hp and 116 lb-ft of torque, along with properly retuned fuel mixtures, ignition timing and full map rescaling. Dinan’s software also removes the top speed governor so the Z4 will be capable of achieving its natural top speed. Producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. In an effort to more effectively control oil and water temperatures, 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.
Increased boost pressure exceeds the turbochargers’ design limitations at higher rpm, potentially shortening their lifespan. Dinan addresses this issue by tapering the boost gradually at higher engine speeds. This approach also addresses the fact that with increased boost at higher rpm the turbocharger temperatures would exceed the intercooler’s ability to cool the intake charge, resulting in a loss of power and compromising the long-term durability of the engine. The tapered boost along with the required oil cooler keeps temperatures within the design limitations so as to optimize output and ensure engine reliability with the added boost pressure.
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.
