Malone Tuning.

"I think the diesel is highly underrated. It’s absolutley fantastic. Yes, there are a few quirks because of the “fix” but the mpg, and power make it a fantastic SUV. I’m a huge advocate for cayenne diesel. Plus with a simple tune, 500 feet of torque is on tap. It’s a beautiful thing."

I have been searching around. I have worked on cars and computers for decades, but I have yet to get into the tuning part. To what are you referring when you mention "a simple tune?"
