Today after fitting a 4 Bar MAP sensor, flashing a file with the right MAP sensor calibration and adjusting the stop screw on the turbo, i had a little race with a 2005 audi a8 d3 4.0Tdi (belongs to a friend of mine), guess who won ? Safe to say he wasn't too impressed with his mighty v8/twin turbo's performance and he made me an offer for the car- which i have declined- not finished with the car yet ! The race nozzle i got are idling bad from time to time but they getting better- only drove 60-70 miles since fitting them !
