ml55 mapping

[ab9758]

Old chestnut, but there's a promotion on popbitch offering £100 off mapping.
Two questions. Is mapping worthwhile (mpg and/or performance) and if so, is it a substitute for asking for a tune up in the next service?

Who is offering the mapping ?

You won't see that much increase on a NA engine , but if it's a reputable company offering it , might be worth having a go.

To give you an idea , on my 430 ( 279 bhp ) they are reckoning a 13 bhp increase and a 17 ft/lb of torque increase for £250 ish ....

You'll get a bit more i guess..

Not worth it with a NA engine IMHO. Assuming you declare the remap you'd potentially be paying more insurance for a trivial power increase.
