C4 100+

Post by Ian1961 »

The previous owner of my car took it to Callaway in Germany for recommissioning not realising that it was a 100+ car.
I think it runs great, but they recommended him taking it to a specialist in Switzerland to have a modern ECU and map. Has anyone done something similar, and if so was there a marked improvement?

Wonder what Callaway Competition couldn't do with it? I mean, they put more 100+ packages together than anyone, maybe...

There's another thread on modern boost injector controllers. You'll need to decide if worth it.

A tune can have a huge effect on a B2k as they were conservatively tuned due to the warranty. You can have to find someone that can tune the old cars at this point.
