My wrx wagon has been de restricted (i had 130 out of her!) Someone has put a little device on the speedo cable so it reads in mph but how do they de restrict it from 112mph? reason i ask is cos i want one of these scoobyecus for it but think it may already have one if it is derestricted?

You are still restricted, but at something like 180mph!

ScoobyECU should be OK, but get to the back of the queue
