Hi,First question, is it worth replacin ECU with something like Megasquirt or similar if im not running Throttle bodies? Iv herd you can get good gains as std ECU is bit restricted.If it is worth it, then as im not that technical with this sort of thing i would need this to be fitted for me.So my questions are:How much would the kit cost me? How much to fit/set up?Any idea on gains? (iv got 1.8 blacktop focus, with 4-2-1 manifold and catback and induction kit, also possibly fitting cams/pulleys)From what iv read the kit can adjust itself so when cruising it doesnt use loads of fuel, but generally is there a massive effect on fuel economy?I had loads of quests but forgot them now.So if you can suggest anything else i might need to know i would be grateful.CheersMatt
