Hello, even if this chipping topic was already enough, it would be nice to initiate a comparison here or to make a comparison of various providers. I find important criteria such as reliability of the provider, reliability, performance, professionalism, of course the price and experience about durability, warranty, problems after the shooting and the subjective driving impression after the shooting. Please for constructive opinions and experiences, because I fluctuate exactly between the in the top Although I have already read one or the other negative opinion about SKN (in line with Wimmer, there were almost only positive opinions), SKN nevertheless looks quite professional and offers at a smaller price (= 750€, because my 180hp TT is year 99 ) a few hp more than Wimmer. Can you even trust or exaggerate SKN here a little bit and Wimmer is a little more reserved. But the Wimmer chip offers a little more torque al the SKN 300 NM to 285 NM. Digitec even offers 310 NM. As far as I am informed, you will not get a measurement on the test bench to give the values to believe. Do I see that right? Besides, performance is not everything (but much *g*), so you should also discuss the other criteria (see above)! So let’s get started… 😉 Greeting, Jörg
