Allows me to gain full control of the timing and boost and tune like a stand alone ecu without over active ecu PID or torque invertention trying to reduce torque. It removes lots of the stupid Bosch routines which hinder tuning for power. Some cars stage2 1.8T ko4 have been seeing around 30bhp30lbft gains, TFSI back to back can see 15-20lbft across the mid range with TiV, some see no gains but much better and smooth torque deilivery, light load driving more refined. I have been using methods like this in my custom maps for a few years now and its only this year I have added them all together and put them in to all my maps.
