to be fair I have not done a dyno myself with the Dinan unit installed. I believe another member here has however from a previous posting in one of the threads , along with the results they (dinan) posted .

Thank you, any chance you could point me to the thread please? I'm so keen on getting more info on the Dinan unit but it's rather limited

search DINAN in the search function. There are a lot of threads on their stuff posted over the last few months. Im sure you can track it down in one of those

I did but I couldn't find one specifically of a C250. Oh well I'll just keep trying to find a bit more info and finally make a decision based on what I've gathered so far.

I know there is a dyno posting on the Dinan website for your vehicle. Honestly for $300 you really cant go wrong , that would be my suggestion

This is great to see! I talked to Terry and got a jb3 then jb4 for my e90 335i back in about 2009/2010. It was great. About 7 maps eventually if I remember right with a meth map too for me. Used to love the ease of setting the maps and options via the tach and speedo.
If thee C63 S version is anywhere near as good once developed I’m in. It’ll be awhile though, my car only has 51 miles on it so still in break in haha.
nice job Terry!
