The 2 best mods that I did on my '03 350 was the Jim Wolf light weight flywheel, which helped low end power, and a Crawford intake Plenum, which helped in the upper RPM's. They made a very noticeable difference. I also had on it the Wolf pop-charger intake, Kinetix high flow cats and a Nismo cat-back exhaust, that combination sounded incredible!
