Question on brakes and DSC - yes i have searched...

OK - i have a used X5 4.4 (2003) that is exhibiting the following two problems - at least i see them as problems having owned other BMWs.
1. The ABS appears to be coming on way too much. Under agressive but not abrupt or severe braking the abs kciks in and the wheels lose some traction, as is the case typicallyw ith abs. I can't turn the abs off so i don't know if the wheels are locking up and then the abs is kicking in. The tires are Michelin Energy LX4 255/18 and almost brand new so i don;'t think tires are the issue. And i know the car is heavy but i owned a 2001 740i that could brake far more aggressivly than this car. I'm wondering is some sensor is bust or off or there is some issue with the brakes that might cause this issue.
2. The DSC is kciking off all the time. Yes i accelerate fairly hard, and the wheels losing traction appear to eb the front ones, but again the 740i never had this issue. If this is how much traction an X5 offers then i don't know how peopel drive the 4.8 - it must be spinning out all the time. I own a 2005 Dodge Durango (5.9 litre, way more torque than the X5) and it suffers from wheel slippage but not to the degree this X5 does (the the dodge is rear wheel drive only). Is this wheel slippage standard fair or is sometiong going on?

Thanks for any insights....
