The Vishnu Proceed software upgrade has been all the rage on the BMW enthusiasts boards but I've personally been waiting for a performance upgrade that comes with the piece of mind of not voiding my BMW warranty. Well Dinan has finally come through with performance and sleeping easy at night.
"Dinan, North America’s BMW tuner, is pleased to announce the introduction of the anxiously awaited Performance Engine Software for BMW 335 models. 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.
"The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration producing maximum output of 384 horsepower at 5700 rpm and 421 lb-ft torque at 4300 rpm. All of this additional power is available from Dinan’s software alone, which is easily downloaded by your Authorized Dinan Dealer in about an hour for 2007 models (2008 model year vehicles require that the ECU is removed and shipped to Dinan for installation of the software at this time).
"*In order to qualify for Dinan’s matching new car warranty coverage, which includes consequential damages, the vehicle MUST be equipped with either a factory oil cooler (not all 335s were equipped from the factory with an oil cooler) or Dinan’s High Capacity Oil Cooler (recommended).
