I just Bought a 93 LX conv 5.0 It has a Cobra Intake, Under drive Pulley's and Flowmaster mufflers. I am Planning on put Shorty Headers a catted after market H pipe and the super 44's cat back system soon. Any other minor mods i can do to help the performance and do i need any type of chip .Its been 15 years since ive had a 5.0 so i am a little out of touch! Any help will be greatly appreciated.
