From a 2001 Audi TT 225. I am going with a BT so won't need my Dahlback chip anymore. This is a chance for anyone with a "K" ecu to upgrade for half the price of new. I got the chip about six months ago from KMDTuning for 699. I am willing to trade my ecu + $350+shipping for your stock "K" ecu. Dahlback Racing 1.8T chip takes your factory 225HP and bumps it to 270HP and 280TQ!! In my opinion this is a very nice very aggressive chip and well worth the 700 I paid for it and is a steal for 350. If you are interested and want to do this I will ship my ECU to you upon payment and you can ship me your once you install mine. I believe VAG-COM is required to swap ECU's so be prepared for that. Any questions let me know. :thumbup:

How does this chip affect mileage?

 

i dunno about this chip... but i have heard from other chips like APR and the other more commonly used ones that under normal driving it doesnt really affect it, if it doesnt improve it very slightly... but obviously under agressive driving im sure it makes it worse but by how much i couldnt tell you
