Dinan numbers are true. I have 2011 x5 50i with dinan stage 4 software and dinan air to water intercooler upgrade. Very impressive performance!! I just did a dyno yesterday and here is the results: 425 horsepower to the wheels and 475lbs torque to wheels. Which means when crank its 510 horsepower and 570lbs torque. I suggest you to get dinan software but dont do stage 4 if you wont do air to water intercooler because it might damage your engine due to overheat. How can i upload a pic ?
