Some of you know I'm new to the turbodiesel Benz world. In my first 3000 miles (nearly 175k for the car), I'm having a pretty doggone good time with it. Domestic biodiesel is fun, too.

How can I liven up the car just a bit? I've still got my BMW E39 M5, which is about to be for sale, and I know the oilburner is never going to make that beast. But as easy as it is for the diesel truck guys to ramp up their outputs (and fuel economy?!) with performance chips, I think something like that must be out there for our cars.

So far I've found the following:

This looks decent as far as output, and is a plug-and-play module from what I can tell. $275ish...not bad!

The turbofroggy fellow is running this. I e-mailed him awhile back and got no response. No pricing that I see on the website, and requires sending your ECU in for a re-flash. Hmmm.

What else is out there, or what other research would you guys recommend? I think a chip of some sort is in my future, probably along with a good WVO system just for the fun of burning some grease. (Yeah, I've read both sides...but it's a car I bought precisely for experimenting!)

Cheers, John
