Weird Noise??
The other day I started hearin' what sounded to me like a whistle comin' from the passangers side. I have a 99 PSD F250, 4"exhaust 3"dp. The EBPV is dissconnected from the turbo as well. So when it's cold like it has been the past few days, I try to keep the RPM's under 2k till in normal temp range. I run DK (white bottle) every tank. So if anyone could help it would be greatly appriciated!!! Thanks in advance!
