Hello, I came on a diesel 3 months ago and really have fun at the 2.5 TDI ( AKN ) it runs as far as I can judge it really great after the exchange of the air mass meter. Now I would like to help him something on the jumps in terms of performance what can you do what you should leave? Thought of a tuning box, steam wheel, open filters and maybe another loader and nozzle. Can you easily install a blow pop off that is now available for diesel or are these harmful to the motor, knows that the valve does not increase the performance but I like the hissing, well the child in the mane. Unfortunately, know me only with color, therefore I hope for help or good advice.
