Sw chip

SW Diesel chip was installed by Steve on my Q7 4.2lt twin turbo 3 months ago.

I can say the difference was suprising, turbo lag gone, acceleration and responce instant, power increase is great, fuel economy is about the same around town as I am having to much fun. Have yet to do a country run.

The only isdue has been on 4 occasions while in 2nd, I have gone to accelerate and the engine has just not responded, like its flooded for a few seconds, then it zll comes good. I would curious to see what it is like set at a higher setting.
