Changed to Synthetic...now turbo whistles more
Is this common? I used the Amsoil Engine cleaner, and then put in Amsoil Diesel /Marine blend. There is definitely more whistle than before, with no noticeable performance change. I also installed a pyro, but its not leaking, nor does it sound like an exhaust leak, just a louder turbo. Still have the stock intake and exhaust on...
