Don't forget the actuator for the turbo, with k03s setup unless the wastgate is pretty much clamped you wont be able to push it too the 240-245 figures.
Also chris why you ditching VVT? Would of thought you would of kept it onto an AGU, considering that on the ETKA diagram its a direct bolt on and gives you a bit more tuning function while you are using a bosch 7.5 ecu.
Also if you look at some EU tuners they do a direct loom replacement kit for AGU to the 7.5 ECU in a kit if you want to simplify things.
