Hi, so I have a tune in just 2 weeks. I made the last minute switch too boost by gear and was wondering what springs to use? My tuner suggested to get 10psi but i dont know what spring/s to get and if I need more than one? Im running a VS Racing MVR 44mm wastegate. I was told to get red and...
I just recently purchased a disassembled y8 head and all the valve springs were tossed into one bag.
Now is there a way for me to figure out which one is the intake springs and which is the exhaust?
of course these are OEM springs, just in case anyone was wondering.
