as simple as possible engine is controlled by ecu the manufacturer doesnt set it for optimum
power and fuel so a remap will give you increased power and in some cases better fuel economy
has to be done by someone with correct equipment costs around £300
remapped my skoda fabia vrs from 130 bhp to 180,vw diesel engines do respond well.Don't think i'd chance a new car just yet,need to make sure any issues ironed out with the model first.
Don't forget insurance companies need to know about any mods to the car,and the increased torque can put a strain on turbo seals and clutch and fly wheel.
I fitted a tuning box to my Navara, as there was a big increase in power and the MPG went up from 26/27 to 29/31 ( I do drive it like I stole it)They are quick and easy to fit (and easy to remove for service time
)Brought mine off ebay very cheap, so if you are thinking about it worth a go.
proceed with caution. Re-maps can invalidate a warranty.
I had my Roadster re-mapped and in the long run it cause so many problems.
1.The power gain was amazing.
2.The fuel consumption went down.
3.The boost potential on the turbo went up and eventially killed my turbo.
4.Then over a period of about 3 years there started to be an excess pressure build-up in my engine which caused the engine to flip into safe mode. (Cured this problem, but in the long run, my engine finally died at 177,000km.
Im interested in a re-map of course as I live in Germany where the highways are much more exciting, but I will waith until I have done 5000km and then look to see which would be the best tuning.
