it is bieing NORMAL it sends torque to the front on aceleration not just wheel spin. this is it anticipating wheel slip.
bare in mind it takes a throttle position input as a main input. not just wheelspin as what most people think.
so driving along in say 3rd gear at around 3k. you floor it and evan befor it comes up on boost the front wheels are already being fed power.
if you think about it. the system has a degree of "lag" in its operation, in the form of relays,pumps,solinoids,actual moving of the fluid and also the slack in the transfercase and front drivelines.
this is the main diferance between 32's and 33/34gtr's the 32's dont run any "preload" on the transfer case clutch. where as the latter is preloaded. to give a quicker responce time.
i know its not very smart,but its job is to asume your about to get up it as soon as you put your foot down.
so dont stess its perfectly normal.
hope that helps
ps... make sure the diagnostic plug is not pluged in. ie bleed mode.
to evan up the rolling diameter
i had a similar problem when i put new tyres on the front and had bald ones on the back. it was fixxed with new tyres on the back.
