Mapping the S50

[virdi325i]

Hi There,

Thinking of getting my car mapped, as I believe it needs one as the exhaust has been changed recently, lacking power from 2000 -4000rpm and the fuel consumption is shite

Has anyone here got this done? If so, can you recommend anyone?

Thinking of taking the car to BW Chiptune? Has anyone used these guys?

What kind power increase is expected?

Sorry about all the questions.... just want to know if it's worth parting with £300 or so.

If it is down on power and drinking fuel then you have a fault that needs sorting before you think about getting it mapped.

+1. get the fault code read and have a good check up first.

Hi I have taken it to BW Chiptune, and no fault codes come up.
What I’m getting is a strong fuel smell constantly in the car interior. (A new tank is also been fitted) might have to take out the back seats, and look under the car for leaks.

First check that the lambda sensors are right for left to right orientation... And that they are before any crossover or x pipes. I have seen this cause exactly what you are describing.
