hello all as some of you no my fiesta is nearley on the road (nearley ,lol)

ive just finished fitting my go-tech mfi ecu and loom as i changed from megasquirt, the go-tech was mapped on a a focous rs with 750cc injectors. my injectors are 350cc and its a zetec turbo i no clearly the map is going to be compleatly unsuted to my spec but ive used it to get it up and running ive as i expected it was running lean so i richened it up a bit and got it to idal and my afr's are between 14-15 and my rpm is 900 but it just sounds rough

should i try opning the throttle a bit more and leaning it off or shutting it a bit ect im a bit lost now lol

i have never maped a car befor but im all ways looking into it. so i thort the best way was to have a go
