alright, so I just ordered my adj. fpr and gauge from ecstuning for my p-16 file I will be running for the k04. My question is that from what I hear the best bar to run it at is between 2.6-2.8 so I am going to go with 2.7. My question is that what psi on the gauge is 2.7 bar? thanks for the info

PS. gauge should be on the feed line right?

2.7 bar = 39.15psi, best to start at 40psi and do some AFR logs. This way if it is slightly rich you can work your way down, better then starting too lean. Yes the fuel pressure gauge goes into the fuel feed line which is the line going to the front part of the rail not the line that is under the FPR. Set the fuel pressure with the car at idle and with the vac line removed.
