The COBB AP for BMWs are more costly yes but it all has to do with the time spend to R&D the tune. It took COBB nearly 2-2.5 years to "crack the code" VS 1 month in the STI. BMWs ECU is a whole lot more complex compared to other vehicles in general. For those of you who have dealt with me in the past thanks for your continued support. For those of you have haven't, feel free to send me a PM and you will not be disappointed
