anyone on here with a blown 540i have plots of a dyno run with the boost? Looking to see if mine is ok before going through with another leak test. I am hitting about 5psi at 5k in 3rd gear...I have a 3.33" pulley and a 5.45" on the crank...also have headers so that would reduce. Without headers I would expect around 9psi with headers I am think would see a few psi of boost loss. haven't had her on the dyno yet though. The tune is still now 100% and don't want to go WOT yet just wanted to see what the gurus think this boost level at 5k is like...I was going to run a leak test but decided to do this test first as it is more fun and I am thinking with this result I probably don't need a leak test.
