Why would you want to put on a FMIC,with out changing turbo.....your not going to gain any power,its just going to lower your charge temps....unless you go for a bigger turbo and re-map etc etc....its not worth it..........
Get on to Dave in STI Tuning for mapping costs, couple of options you could go for, all different prices. As said above, without a turbo upgrade,your wasting your time with a frontmount
