Re: BOV advice anybody?
BOV's don't work on our trucks because these engines don't have a throttle body. BOV's function off pressure spikes on the compressor side of the turbo. Since these engines don't have a throttle body with a butterfly valve that closes the intake, there isn't as much of a pressure spike as you would see on a gas engine. The only way to get a BOV to work is to hook up an electronic unit that opens up when you let off the accel pedal, but even then it isn't worth the high cost and won't help anything.
To test, accelerate your truck hard, then just suddenly let off the pedal and watch the boost gauge. You won't see much of a spike. Now, do that with a turbocharged gas engine.........
