No, tuners are not bad in the long run. Your engine life depends on how you drive your car. I bought my SCT Xcal 2 from Lightning Force Performance here in Houston Tuned for me and my mods. I didn't want 87octane so they did a Street Tune and a Race Tune.
does the exhaust have a low rumble or is it more high piched? I rather have a low rumble I like more bass my exhaust.
I dyno'd a few months back and picked up 57rwhp with a C&L Cold Air Induction System, DiabloSport Custom Tuned Tuner, Bassani Axle Back & Bassani Mid Pipes w/Cats. The benifet to adding the Bassani S.S. Mid Pipes w/Cats is this kit comes with Off Road Legs.
