I do this podt for doubts that I have I have curiosities I have a 335xi n55 with SteamSpeed ​​82r completely fbo with dorch stage 2 because the tuner told me that I should buy it I put it and everything and when I am ready to tune now they tell me that the factory injectors they are limited to 500whp and I don't know what to buy because I don't want port injectors in my car because it is my daily car, so I was checking and they sell an upgrade kit worth 1600 but I don't know if there will be others like the m5 ones that hold more power that mine all the suggestion that they can give me

Check other threads, there are a few on using the S63 (?) or the nostrum. Check this section a few pages back and the N55 section for more specific threads.

Also, you didnt specify the fuel, like i said in your other thread, people make over 500whp on stock injectors all the time.
