hi if i bought a TDI PD Diesel Tuning Chip for my arosa. are there any bad side affects for my engine?? it says it will increase the power and mpg. has anyone done this and would they recommend it?
kind regards carl

I was once tempted by them, but never got one. I have heard thery can do more harm than good, they simply over fuel your car, which is never a good thing!

If you want more performance and better MPG when going easy then the only option is a remap
