I have Rjwc full exhaust system,Rjwc air filter and Rjwc efi controller. My fatherinlaw has a standard 2016 model cforce . I'm quicker than him and have more punch from 40-71.
And we done a 370 mile trip on road couple weeks ago . I used about 11litres of less fuel than him.
I'm ordering heavier Dr pulley rollers and new belt so should top out around 75mph .
