In stock form it will idle when cold at about 1500/1800 rpm (can’t remember exactly, but someone will confirm) for about one / one and a half minutes. If it’s been mapped out it will drop to about 900rpm in next to no time. I.e. not annoy your neighbours all the time. :lol:

Where abouts are you based?

I’m based in Bolton

Do you know roughly the cost of getting them open and mapped?

Depends if you are carbon cleaning etc too and whether that is a basic clean or extensive. Plus port, etc. Speak to MRC or CM Tuning (Chris, ex MRC based in the north).
