I believe the transmission in the X5 35d is a ZF 6HP28 (formerly 6HP26 TU).

It is rated at 700 Nm, or 520 pound-feet of torque!

Now, the chip does not void your warranty any more than a cell phone voids your warranty. True, if your Bluetooth gets fried and they determine your aftermarket cell phone did it they will deny the warranty coverage... but the rest of the car is still covered. Likewise, if you burn out a turbo and they determine you had an aftermarket chip it is your problem... but every other system on the vehicle is still covered. There is a lot of misinformation out there.

Truth is, most chips "trick" the ECU into delivering more boost... normal boost that would normally be used at high altitude, hot operating conditions, etc... nothing that far out of the ordinary. As a result, the rest of the engine's systems compensate with more fuel, unique timing, etc...
