Through careful remapping of the factory ECU and countless hours of testing, Velos Designwerks is pleased to announce the release of its performance software for the N63 BMW 4.4L Liter Twin Turbo V8 Engine. Producing an astounding 402 hp and 440 lb-ft off of the assembly line, the Velos Designwerks engineering team has been able to increase this powerplant’s output to a peak 455 hp and 532 lb-ft of torque.
The actual peak gains over the stock car is 58 hp and 72 lb ft of torque.
The Velos Designwerks X5 5.0i Performance Software and X6 5.0i Performance Software involves a remapping of several of the factory’s ECU maps including, but not limited to, the fuel maps, throttle maps, ignition maps, and limiters. The smooth increase in power delivery as well as the increase in torque brings this nearly 5,000 pound vehicle to close to M levels. With this 12% increase in horsepower and over 19% increase in torque, the N63 4.4 Liter Engine’s true potential is now fully unleashed with peak HP being reached at the new redline of 6800 rpm and peak tq at 3500 rpm.
While there are and will be other options available on the market, the Velos Designwerks Custom ECU Tune for the N63 BMW 4.4L Liter V8 Biturbo Engine produces real gains throughout the powerband that one can realistically expect to duplicate on their own. Several options available for this upgrade including the Velos Personal Tuner which allows you to complete this upgrade without sending Velos Designwerks your ECU. Stage 2 options are also available for vehicles fitted with full exhaust and downpipes for off-road use.
