Does anyone know if these actually work, or are they just another gimmick?

Get a proper remap, boxes are naff.

I have a similar one on my CLK. Yes the remap is much better but as I got mine secondhand for £25 delivered it was an obvious choice and to see if it was as good as the £400 tunit I had on one some years ago.

Don't know if the performance gains are accurate on these type of listings BUT I will tell you this:
Throttle response is MUCH better and the torque seems greatly improved.
approximately 5 MPG better economy and I would recommend it as a cheaper alternatie to a remap.

This is the one I have and I wouldn't be without it now:

My feeling is that you can sell it on for at least half of your outlay if you want a remap later.

Just don't buy the resistor in a box that messes with the IAT making the car over-fuel. They don't work!

I use them and I have never had an issue in years.

I use the Speedhawk type.

I have this, map/stock your car as often as you like & it is a basic code reader!

I looked up the Speedhawk and found that there are four different power outputs listed for my C200 CDI W203. Is there an easy way of telling which one I have?

I think the dvla website can help. Or euro car parts can look it up.
