Fitted a decat pipe to my zs td today what a dif its made pulls so much quicker and smoother along with the tunning box k&n panel filter and the boost set to 19psi it such a nicer drive 2nd 3rd and 4th have so much more power
Yeah a well set up td should get 150bhp and 240ft lb of torque where a 180 will get 200bhp and 180ft lb torque
The td will do between 40/50 mpg
the 180 will do between 20/30 mpg
