I believe the bt maps are still the same ones from when jonnyc had them. May have had slight tweaks over the years. Speak to Kev direct and ask him.
I have a K1 being mapped by Niki at the start of map using the Nortech kit. Stock engine, but things like a hard cut rev limit will be added, gear based boost, pops and bangs like the rs focus and a mild launch control. All using the stock n75 valve. Using boost controllers is just a way of working around a map that isn't specific for a car.
I will try and find the vid showing the S3 injectors flowing more than the RS4 ones. There is also a TTS out there running 600bhp on S3 injectors.
