I was up at Star a couple of weeks ago and the demo car which has a forge FMIC fitted now aswell has a full exhaust and air intake with a new custom remap he trying the night before. He was saying that he got as much out of the standard turbo as possible and it was running 290bhp and 314lbft I saw the graph and it looked very smooth. His was a later engine with the new type of fuel rail which apparantly is good for remaps. Think it was a F type he mentioned not 100% sure on that though.
He never mentioned if he was going to put another turbo on it. Sounds like if it is running 330bhp it must have a bigger turbo on it.
