okay I have a serious issue going on with my truck.
at around 1900 2000 rpm. I'm hearing air leak into my cabin. sounds crazy. it's almost as if I can hear the motor build boost and it's bleeding off into the cabin area up around where the window meets the dash and firewall.
put the truck in park and rev the motor and it does surge.
but only when driving under load will I hear the surging noise. no once again it's not my turbo I know how compressor and turbine sounds under load this is a different type of leak or surge.
