From the factory they only did around 30mpg so thats a 73% improvement
I only get around 35mpg at 14.7:1 AFR and 35-38deg of advance.
My measurement style was like fill up until petrol pistol first clicks and stop. Then drive to other city and fill up with similar petrol pump. My intake manifold has been matched to head and my head is modified too. Car weights 930kg with spare tyre.
AFR 14.5-15 and 42-45 spark angle
