Yes you do need to upgrade to mass air on that cam. You may need the idle plate too.

look for a crower 15511 cam if you want to stick with speed density, its what a lot of people run with lots of success.

you could get all the stuff for mass air pretty cheaply at a pick-n-pull, I would imagine.

I had a TFS stage 1 cam in my car for a while while I was still running speed density. Expect the car to idle sporadically, ranging from 900 - 1500. It didn't surge. It sit there, but never at the same RPM. It would randomly just jump from 900 to 1200. Also, the car will run pig rich. Whenever you stab the pedal, you'll see a ton of smoke out the rear view mirror. My car got 8-10mpg while running speed density (its now around 15-17mpg) And to top it off, you'll spew unburned gas at idle. If I were youI'd plan on making the change from SD to mass air at the same time you do the cam. The car wasn't down on power by much (trapped at 106mph), but its drivability was in the shitter.
