The M400 I bought is running a 1.1bar Roush map Im told. All else is standard.
Is anyone running the same map? Any good ?
Do the 3" exhaust make a difference if added? Think of this as next mod.
When do I need larger injectors? 42 at the moment I think.

I am probably running a similar map as it is also a M400 with Roush exhaust (I presume you have the Roush exhaust with the remap?) and remapped to around 1.1 bar. Is it any good? - Well mine is fine and pulls strongly and smoothly right up to the rev limited. Is yours any good - I have no idea - is it not running well?

Why do you want to change the exhaust or injectors if its running well?

nope, no exhaust yet. Was wondering if exhaust is worth it ?
Why I asked was that I was made aware that the roush runs rather lean, which is not condusive to longetivity of our turbo lump. A bigger exhaust will lean it more. If its really leaner I cannot say, but i should be cautious and ask as someone here may know better.

running more power gets a bit complicated

you will need bigger turbo's / injectors / Clutch
