(Sorry for double mail; the thread is already in the A4/8D range, but here more answers are assumed, which the question is relatively general. ^^) Hello dear Audi fans! The following question to you: I will go back to school from August to make my master. ^^ Must then travel about 100km every day. To 95% highway. Have thought, that I now, where I still earn money my car chip. I heard that you can save fuel on long distances by driving normally. D Once in a while I just need the “kick”! Now the real question: you can also “chipping” the engine by cutting the electronics individually to the car. Heist software adapt, to the test bench, re-adjust, re-test bench, …. and so on. I heard about this method and tend strongly in this direction than just clapping the chip. Has anyone had experience with it? Is this method w I come from the vicinity of Frankenthal / Ludwigshafen / Mannheim, but I would already drive about 100km to get this done! My Audi: A4 Limo 1.8T 150PS Built:99 120,000 km Facelift K&N Sports air filter Blow-off valve ^^ (I love this sound!!!) Timing belts / V-belts and all the pleasures made completely new 100km ago Oil: 0W30 Longlife Full-Synthetics I really care a lot about my Audi and ic h have to drive for a long time! That’s why the “tuning” should be gentle for the car and not so that I can get a new turbo after 3 months. ^^ Thank you for every tip! Greetings, Thomas from Studernheim. 🙂
