[M535i]

Hi,

I’m thinking of remapping a 420i fastback. I checked the torque convertor in the AT can take the extra torque of the remap with going over it’s (AT) max torque figure. My question is what is the max torque rating for the rear diff? I’m thinking of Superchips Powergate. Any ideas on exhaust gas temp, do I need to put in ugraded intercooler?

Thanks
