Yah, take the chip out. It's the cause of your problems. Tuning outside of OEM protocols requires a real life tuner, calculating the variables of your particular position on earth.
An out of the box chip gives crap calculations that are assumed to be viable for all variables, but they aren't.
In short, send the chip back, and watch the car behave again.
