Just bought an M3 with AA gen 2 turbo,I am new to turbo stuff. I do know that AA did not do the install. I have no need to boost over 14psi(at this time). Other than calling AA all the time can any of you guide me in the right direction on tuning this thing. It has a recent AA upgrade chip, a recent turbo rebuild, I installed a Tial 40mm wastegate .7 bar spring ,it has 8.9 compression, a blitz bov which I converted to a compressor relief valve( works great),a blitz boost controller spec-r. Where do I install the egt temp. probe (be clean now). How do I tell what # injectors I have. I know it is a lot of questions I just hope you can answer some . I also have a split second piggy back fuel/timing comp ftc1. Thanks J.T.
