Guys, what is the average gain in horsepower and torque by going from 1.5RR to 1.6RR on the stock cam? Has anybody dynoed their car after they installed the 1.6RR? My car is pretty much bone stock, and is there a noticeable sotp improvement in power and torque. Does it change the sound of the exhaust any?
Thanks
