Purchased a lot if RaceChip Ultimate from me to stack it up on top of MPPK.

Shall do....but I also saw complains of engine chirping being experienced by reputable members. Now, it could be the specific setting they used, but, based on private emails to RC in Germany, I was told not to do it.
Obviously, I don't know what the exact risks there are, but I do know that paying $1200 for a few more "horses", is like betting for a wounded horse to win the Kentucky Derby!  |
MPPK is like making your X5 more athletic and giving it a boost in power, low end torque, and the transmission shifts become more crisp.
Adding RCU on top of that gives you a very fast 35i. I've reviewed this if you want to search my thread.
