This article almost seems to have a hidden agenda in it ...Nothing but negatives. Chipping your car is in fact safe - as long as proper testing is done on everything. APR makes chips for Audi and VW, you will not find a better chip company out there for those cars.As far as emissions and vehicular service goes, you don't need to worry. If you get a good enough chip, you can actually just return your car to "stock mode" and the dealer will not know the difference, nor will you fail an emissions test.The best chips that I have seen are where you send your ECU to the company, they solder in the chips, seal the ECU back up, and you can turn it on or off with something as simple as holding the cruise control button for 3 seconds. What is great about that, is that the dealership will NEVER know you did anything, as long as you keep it in stock mode when you take it in. The dealership cannot just go into your ECU and other parts of the car WITHOUT your permission, hooray!Unichip looks like it would be easily removable, and from what I hear, there is enough R&D work done that you don't need to worry about blown engines.That being said, of course problems could arise, but that's what happens anytime you mod your car. The article just seemed to portray chips in such a negative light, I just had to step in.Happy Chipping!
