Low power after nozzel swap ???

A few months ago i swapt my nozzels to warp 3 , I installed them without pop-testing them.
And then I got it tuned by Malone tuning.
And now my car goes like crap, I have bad acceleration, but from 4000 rpms and oute its fine.
Sometimes the motor can start to shake , when its running idle.
I have tried to adjusted the Iq but it dosen help, it only gets worst and its start to shake like hell.
My old stage 1 tune was better , but a lot more smoke that resulted in turbo build up.
So today i was checking group 13 in vagcom, and i got this :

Is this normal or does it mean i have to get the injectores pop-tested and adjusted ?

They should be pop tested first to ensure proper opening pressure also could be dripping and not having the correct spray pattern

Those Group 13 numbers don't look bad at all..

If you reprogram your Stage I tune, does the car improve?

yeah it gets mutch beter, can it be that the tuner have adjusted the timing to low maybe or something ? i dont know if the tuner is abel to do that whit only programing , i had the chips sendt to me by mail

If the tune improves it then I would think your issue lies within the tune itself.
