If you have an limited and you are use to muscle car performance You should just get a SRT-6 and get it over with.
then get all the Needswings performance stuff . with just the bolt on's you can get very close to 350 wheel hp .
and 11.3@ 107 in the 1/4 mile. with the limited you may get14.5 at 90mph with the mods you do to a limited add a little
to that for a srt6 and then $$$$$ and go faster than the most mustangs and or camaro and believe it or not it is faster than a hemi charger .
