So i bought a PCV and had a guy dynotune it. It runs so much nicer, it loves to be opened up! i have a akrapovic slip on the only main mod. Only problem is my fuel economy dropped about 10mpg+. now i know the fuel economy may decrease but that seems like a pretty steep trade off. Also to mention, there has been a build up of black residue coming from my exhaust assuming from gas. i also run recreational gas and hadthat in the tank while it was getting tuned. What do you guys think? should i try to mess with the map or go with another map to find online? Thanks!
