can you resize that pic?

A 2011 F-350 drove by the wife and I yesterday in the Wallyworld Parking lot. I asked her if she heard anything weird about it. "NO"...told her it was a PSD as well and she said "why isn't it as loud as yours?"

it would be nice to have a little less clatter...but then again that noise is part of why I love having a PSD

When it's cold out - boy is she loud and cackly. Reminds me of the commercial where the engine jumps out of the car........

Jody at DP-Tuner has a drive-thru tune that adjusts the injectors so the engine quiets down.

Different injectors make a world of difference.

HEUI injectors are loud.

I thought diesels clattered from the high compression ratio and cylinder pressures... how does it adjust the injectors to quiet it down?

Not being a tuner, I don't have the knowledge to answer your question, plus, I've never asked Jody for specifics. I just remember him telling me it has to do with the injectors and the tune, when he was live tuning my truck.
