Recently sold my S6 for a A8 4.0 TDI. And although its awesome, smooth and still really just as powerful as my S6 without the revs, I want to have a go at "chipping"
Have sort of been looking at 2
They seem to be the same company but one system is more adaptive than the other, one just has various ECU maps in it, the more expensive one actually reads your ECU and adapts to suit (Or so it claims)
The figures however are very different as you can see..
One gives much more BHP and the more expensive gives less BHP and more torque.
Just wondering if
a) anyone here has any sort of experience with any of these companies or types of tuning chip
b) what difference do you think each of these will make in the real world? i.e. difference between more torque and bhp in normal everyday use.
Any comments or help appreciated. Or any other way of squeezing more from the beast!
