Is the ramp profile slow or quick? I was wondering does this make a difference in performance (torque, idle and HP).

Requires modified Mass Airflow sensor.
What does that mean? Get the mass air sensor recalibrated?

probably saying that the stock one can't handle the surging air coming through it because of the cam.

i dont know why they have that on there anyways since anyone who swaps cams probably already has all the bolt-ons..

I would like to know if they are refering to stock or afterrmarket also sense some of us on here experience surging problems after a cam swap.

i think they are referring to stock.. or they may be referring to the fact that if you swap heads and intake as they also reccomend, you should switch to bigger injectors which require a different mass air calibration.

TFS#1 appears to have a nice aggressive ramp rate. Advertised duration @ .006" is only 275/279 while dur @ .050" is 221/225. Not bad. This is comparable to some of the CompCam Xtreme lobes. Well, at least its alol closer in ramp rate to the Xtreme line than to FMS's ancient cams - LOL!

BTW - The TFS#1is a good cam for a 302ci/306ci IMHO.
