I behave a DS4 135 bhp has any chipped there's yet and is it worth it,do you get any benefit from it

When you say chipped, do you mean remapped?I have 160 bhp Hdi so I wont be going down that route
Have you thought about a digital tuning box..Does the same , but is removable

 

[Johnboy]

Chris thanks for your response it is the removeable type just wondered if it is a good thing

 

[Chris]

Depends

There are cheap resister type analogue ones that fool the ECU into
delivering more fuel

Then there are the much more expensive digital ones, which alter many parameters..These
are the ones you need
