Any body has felt that while going WOT if you press slighty the brake pedal, the car makes like if you release the gas pedal? the car stops acelerating, and at the moment that you release the brake, the car launches again?

It only occurs if you have selected any map different than 0, in stock mode every thing is normal... it's some kind of UTEC "feature"

 

the car has that built in from the factory. Its the reason you have to pull the brake fuse at the drag strip to do a burnout.

 

With the UTEC in stock mode, I can press both pedals without any strange effect, I have tried it tones of times for heat up brakes.

 

Any body has experienced this on a manual transmision Z???

utec in stock mode is...well the utec "letting" the stock ecu control everything....thats y it doesnt happen then....the z is a strange monsta like that....

 

But if I switch off the UTEC, I can press both pedals without problem, it only happens when the UTEC has the control

 

well then there's something wrong with your car, you should not be able to push both pedals and have the engine rev as the ecu cuts the throttle when you apply the brake.
