Could someone tell me, is there any problems to performance if egr is sealed off completly?

Risk of detonation at part throttle due to higher combustion temperatures. The EGR system is there to reduce temps in order to limit NOx production for emissions. You can get someone to burn you a chip with the EGR enable temperature set at 300° and that will reduce likelyhood of detonation.

yup exactly that
I have mine disconnected, for awhile now.
I've had light throttle detonations - so I just avoid light throttle
I just got a chip burned, but havent tried it yet.
