Ok sounds like a plan. Don't think I'll be going on e85 anytime soon.. Haven't even seen it in petrol stations yet!!
I remember the tuner last time saying the next steps were "high flow turbo back exhaust, bigger turbo, injectors".... so maybe i'll leave injectors off the list for now and get them to tune and see what they think..
Also, worth getting a BOV while i'm at it?? They seem wanky, but have some benefits I read
