Hey all,

Anyone out there have their ecu chip reprogrammed by Powerchip? What difference did it make to the performance of your car? Anyone have any before/after numbers...0-60, 30-50, 50-70, MPG, that sort of thing? Thinking about doing it to my SLK230.

Thanks

Mike

I had the Powerchip upgrade and I have a pulley. Both are about the same price. I would get the pulley first. It made a huge improvement. I didn't notice much change from the chip. I did not run a dyno on either.
