      I'm currently planning on adding bosch 550cc, IE high flow fuel rail, 4 bar bosch FPR, to my mk4 gli with a stage 2 unitronic from the previous owner and I need to know if they'll be a straight bolt on or if I'll have to contact unitronic and switch the ownership license and get the car retuned.

      Anytime you change injector size or fuel pressure, you will need to be retuned.

      I have to ask though, why are you doing fueling upgrades with a stock turbo?

      The injectors and 4bar FPR will only make you run rich, even if you could tune it to run well on the stock turbo it wont benefit you to run those injectors and FPR unless you upgrade to big turbo (GT28RS range).

      For stage 2 software on stock turbo, just retune as long as you have upgraded downpipe, FMIC or upgraded SMIC and upgraded diverter valve.

      I'm planning to change the turbo soon but because money it'll be a little later down the road.

      You will definitely need to get retuned.

      The injection calculation uses a table for the response time of the solenoid in the fuel injector vs the current battery voltage. The response time will be different in your new injectors. There is also a constant value that relates to the max flow rate of the injector that will need to be changed.

      As stated, any time you change to a new injector, or edit your base fuel pressure, you will need to get retuned because you will require a new injector constant and battery voltage compensation table.

      Hold off on buying fuel injectors until you buy, or at least decide on what turbo you will be using. You want to make sure you buy injectors that can supply enough fuel for whatever airflow your turbo is capable of

      Will I be able to edit the fuel using the maestro suite? and is there a better programming tool?

      You can do that with maestro. I havent messed around with Maestro for a while, but my experience with it hasnt been great. If you dont want to learn to tune, which isnt exactly easy, take it to a local shop or have Gonzo (is he still around?) remote tune it for you or something.

      I learned some tuning when I was in school to be a mechanic and I'm doing mechanical engineering now so it shouldn't be too hard.

      Im in school for Mech Engineering too

      Its not necessarily difficult to use Maestro, its just the fact that theres no support for the program anymore, and you dont exactly have full access to your ecu like you would if you were to tune with Nefmoto software. Maestro is basically just pretty wrapping paper that makes the whole process more user friendly. Im all for people learning to tune, but just be aware that theres no support from Eurodyne once you buy Maestro, and the help thread here is pretty dead now too. Basic tuning theories will still apply to shaping maps smoothly so interpolated values arent on steep slopes, and getting a general timing curve laid out isnt any different than a different car would be, but dealing with the whole torque based load calculations can get a little convoluted.

      Anyways, if you plan to learn how to tune, get familiar with the Nefmoto site, and learn what you can over there because you wont find a better ME7 tuning resource on the internet
