So I've searched for chipping and found few posts on chipping of X3 diesel models. I understand the potential warranty issues etc but looking at Racechip and the stated gains in hp/torque and improved economy it seems an intriguing prospect! Anyone have practical experience if this and comments on the experience? It's not something I would do until the car has been run in but I am considering it once that's done. Cheers!

i asked about this before placing an order for mine and my sales manager mentioned that Dinan chip is available and increase HP by 100-120, and Tq by 60 or around there. He was reading this off of a list and its very expensive but covered by warranty. $2000.00, This is in Ontario canada pricing..
