What can it do?
It's got bags of Torque, pulls from nothing, loads of mid range, gets rid of gas on high capacity engines so they do not over heat,
noise is VERY acceptable ( so say the customers) and will still beat the opposition
on a 1/4 mile blast. Oh and purrs along very easily at 80 mph (GPS) ( if your machine is capable).
