Am looking for more performance, 103bhp as standard, i am already running a 2.5 de-cat system and a panel filter (induction kits don't seen too beneficial on an M10).
What else can i do? cams? ported gas flowed head? i have no idea.
Yes i can put better plugs and leads etc but that doesn't give a performance upgrade as such.
Thoughts, ideas or what people have done before?????
now that could be fun to do.
