N54 Injector testing, Car hesitates and stutters 

You'll want to put new seals in if the injectors dont remain seated perfectly theyll start move around with the tension spring and hone the bore. Causing way more trouble..40 dollars is not worth a bore repair kit or new head. Might be your post 02 sensors there responsible for fuel trims..

I’ve never seen a turbo on the right side

So what was the problem ? I’m having hesitation issues also?

Use lucas injector cleaner in ultrasonic jewelry cleaner will take wake carbin build up better than a whipe..sit the the injectors heads in basket for 30mins..

How much bhp is your car? and how is the auto transmission holding up in it??
