Tuning Box: White Smoke from Full Throttle?

Hello,

My tuning module has been installed in the vehicle for quite some time now.

It has two screws: one to increase the idle speed and one to extend the injection time.

'I've noticed some strange white smoke coming out when the scooter is under full load (with a bike rack and a lot of luggage). It doesn't happen when it's empty, or even when I turn on the motor. It only happens when it's fully loaded!'

Is that white smoke normal?
Is the engine at risk ?
Should I turn the injection time extension back down a little bit ?

Vehicle: Volkswagen Golf 3.
Engine: Engine code: AHU, 1.9L, 90 hp.
Engine modifications: K&N 57i and tuning box.


I would be very grateful for answers to my questions.


Best regards,
