I have a 97 roush stage 3 with a pulley on it. My battery went dead and now i think my tune is all messed up because now im getting check engine codes and it seems to have more timing in it now. What is the best tuner for my car? SCT is what I'm thinking. I am reading that my car has a different computer than the newer ones and i cant just buy any tuner. I wanna be able to adjust things myself without a dyno. What do ya think?
