I like how Dinan says it "Performance without sacrifice"
Also with every BMW factory update, Dinan will change their program file to accommodate and each Dinan dealer will then update your ECU for free !
I use a independent Dinan dealer in socal Autohaus Frankfurt. They will flash your ECU and let you test drive before you pay. If you are unhappy (which I doubt you will) they will re-flash with the factory file all for NO CHARGE !
