147 is low isnt it?

I get 144 with 162Bhp on my stock 172.

Probably a fault injector tbh. injectors fail on these engines quite often.

What mods does it have for that power?!

You do know it'll need remapping if changing the injectors? Unless your running Megane injectors anyway already I guess?

Interesting to know what modifications it has had
