If the balance test was okay with those leakback results your injectors should be okay

As discussed earlier, I have been unable to get the injector test function in vida to work. If I have the opportunity to test with another system I'll definitely do it.

Machine 2 aluminium discs with in one a threaded plug for a compressed air connection
Plug one in the hose you take from the egr plenum and the other in the hase after the filter/airmass sensor
create pressure and listen if nothing is heared , note the pressure and leave it a few hours to see if the pressure dropps

I did do a pressure test on the intercooler last weekend and it seemed to hold well - it very nearly did me an injury as one of my home made plugs was fired out at high speed

I only applied pressure from the join of the flexible hose/ hard hose (under engine) to the flexible hose at the egr plenum. I figured that if pressurised from the maf you will lose pressure into the pcv system - pressurising from the turbo inlet would be preferable.

I also removed all other inlet and charge pipes and found no damage by visual inspection.

Pcv is a good point to not overlook but that could be squeezed off to measure the whole intake at once
Concerning the vidatest mine didnt work as well with the illegal copy
But for 20pounds you could do it at the dealers ,could save a lot more money at injectortesting and pipework
