hi
I was thinking of starting this thread in hopes to obtain a guideline with Datalogs for different single turbo setups on various n54's in the forum and if it grows enough and admin agrees we could make it a sticky thread, not sure if it's limited to just me but currently find it difficult to locate the below info in one place, if you want to start your single turbo journey/ change your turbo for a different application eg from street to a drag car or just simply want some data for future improvements and knowledge to meet Certain goals for your N54. I did search the forum but and im sure there are a few posts but they don't all contain all relevant info as per below.
I have put a list below please feel free to contribute to help others make more informed decisions on their build, this is an older platform now but still feel there's many decent builds out there and is still relevant, I feel that real data from other builds will help.
