A big thanks to Ric at unicorn developments today for the DPF delete and remap on my A4!! The car feels totally different and much smoother with bags more power and torque! I couldn't recommend him enough to anyone having DPF problems or even those who are not and having problems ""YET"" and just want to do away with the DPF as they are sh**e and release more power and stop the engine being strangled. Also a little added bonus is the turbo whistle it sounds amazing lol Thanks again Ric you have done an excellent job!!!! FAO Ric my mk5 golf gti will be with you soon so you can work your magic!!!
