The tornado is garbage. its been proven time and time again to do absolutley nothing.The best place to get upgrades, is in your garage. Go to the hardware store and buy a 3" outdoor lighting post. Take it to your muffler shop, and have them mandrel bend it, so it will fit. Instead of a $150 intake, you have the same performance for 1/3rd the cost.Other cheap upgrades include a throttle body spacer, a header spacer. They are about $30 each, and they will give you hp (i got 7hp from the tb spacer and header spacer on my probe)port and polish the heads-cost:Freeloose weight: gut everything you can. Do you really need that spare tire and jack in the trunk? I mean if you dont know many people that will drive out to the middle of nowhere to help you change a flat, then you might just want to keep it. replace filters-Under $30replace spark plugs=$50Thats a cheap start.
