I've heard good work from engine dynamics also!
I do think your chasing that also, clios have all sorts of noises, even mine and it's only just 3 lol!

Im an anal, perfectionist Virgo. Defeat doesn't come easy. But if yours has 'noises' - there may be no hope for me.
To be fair my mates GTR sounds like a Montego from cold too. Showing my age now....
