Tuner for my 97 Roush charged 4.6
I have a 2002 motor in my 97 with a roush supercharger with a pulley, its the old style with the supercharger under the intake. It pulls like 9 psi, and i don't think that it has been tuned. It runs great but I think i hear it spark knocking, is it my imagination or do I need to get a tuner? If so, what do ones are good? How could I tell if it has a program on it?
