never had experience with n/a legacy , but I have the turbo 05 model and running raw super for about 3 yrs now =] ..... so give it a try , just top up bit by bit with the super and listen for that ping or sputter =] it should work cause my cousin has the n/a 05 wagon and he has no problems.
Yes champ you can use super,the vehicle ecu will retard timing to compensate ! The only problem you WILL face,the car wouldn't be as aggressive as before !
