Hi all , this is my firts post so i hope you can help me.
i have a 328 turbo which is pushing out more power at .5 bar than it is at .8
i am running a garret t4 turbo with 6 328 injectors and 2 extra injectors and a perfectpower 6 chip ( piggyback system),and ngk8 cold spark plugs
I was told reason for power loss at .8 bar is maybe the ignition or the turbo is to small.
please help
