I hear these guys do a great job in adding some serious power with their ecu re-programming, especially if combined with upper, lower pullies, exhaust.

Has anyone used them to reprogram their ECU's? What was the result?

I've spoken to the owner on the phone. Apparently, they've been doing this for a while. He sounded pretty knowledgeable about making real power with
a stock XKR.

Thanks, guys. Ed.

 

I posted a link to them almost two years ago, including the graph, which, one sharp eyed poster realized had a typo in one area. (as I had) Every response was critical, even though they did not really know anything about them. I suggested that they call them and speak to them to see what they thought. No one did. One response was that the 30 hp boost would be "insignificant". May be a different group now, let's see how it shakes out this time.
