I have the m48 pro and it's great apart from when it's cold it don't
like running
but it's fine after it warms up I just start her
up and live her running for 5 min's and she's as good as gold 8) I
gaind 50hp and 70lb's of torque just fitting the motec it's a verry good
bit of kit, If your cars all ready running well you might not get as much,
As mine was running 5hit at the time, also you have your launch control
ant-lag and traction control as well if you want to fit new wheel sensors.
