hi,</P>


We own a '98 A4 avant 1.9 TDI 90 HP. When you drive it you always get the feeling that your on the road with more power...</P>


Now a few days ago, searching on the net for possible tuning there was an artical about "what is tuning". In the text there is a topic called "no need to tune? </P>


In the text they use the example of the 1.9 quite often. And what do i read in that topic... They've already had quite some 1.9 90 HP's that produced 115 -118 PS !!! would it be .... :-)</P>


Another surprizing thing they mentioned was that the TDI's in an A3, A4 and A6 ( ore the other brands that use these engines) are far from the same.</P>


pretty amazing :-)</P>


greetings,</P>

Plug in electronic tuning modules always available on ebay. These claim to increase power 20-30%.They alter fuel mapping and not turbo boost.Quick fit and claim no effect on reliability so long as your car is in good shape.</P>


For comparison, Iv'e an A4 Avant 110 redeye which has decent power yet still gets 55+mpg</P>

be warned - much of the stuff on ebay is garbage and will either do nothing, ar harm your car.

I would suggest you go to a reputable tuner if you want to tune your car.
