Not sure if this is the proper place to post this question. This question is something I have always wondered and I am sure other tuners in training are interested in as well.
Well adding boost (SC, TC, PC ect) how do you control the boost output of the engine? For example, I see a lot of ?set to max 6psi? or ?made X amount of power at 12pm I, but we turned it down to 10psi for safety?.
How are they turning down/up the boost? How does the pulley size affect what is commanded?
