I will use a superchips custom map on my Fabia vRS with a bunch of mods, they won't touch propane annoyingly, but due to recent engine enjoyments I don't care about this yet.

The main reason for me using them at the moment is to get a decent map for what I have on my car, dealt with locally by APS in Brackley, so they are happy the engine is running well.

In time, I will use my second ECU to get a more custom map done by some other tuner, probably chipped UK, could be some other company, when I have a bit more time and have recovered from the repair costs so far ;)
