E53 X5 4WD. Mod able?

[Tymatk]

Hi

Was just wondering if the E53 X5 4WD computer can be modify so it will allow me to dial in the amount of torque to front and back the way i wanted it?

Say i can dial in 30% front and 70% back or even 10% front and 90% back, is this feasible? I used to be able to do this with the Nissan Attessa on my Semi track R32gtr pending on weather condition.

Also can i modify the Transmission Cooler to AIR COOL and slightly larger?

Thanks
