Hey mate welcome to the forum
sign up for full membership, loads of info on here about mods etc.
Most people go for a k&n 57i, then a new exhaust system (either full or in parts), don't bother with chips or remaps for now- exhaust system and filter should see 165-170bhp.
Or you can go down the mountune route, a little more expensive but they're Ford approved and never heard a bad word said about them on here. Check out their website
