2001 Subaru Legacy Much Should Pay On Tune Subaru

This all depends, it depends on what plugs you use and what all they want to replace, ie fuel filter, air filter, cabin air filter, pcv, plug wires or coil boots, are any belts needed and so forth. Also what is there labor rate. You should expect to pay any where from 150 on up with today average labor rate. Hope this helps some.
