usually canned tunes are tuned according to your current mods.
if you drop a pulley after you put a canned tune on, you are going to need a tune.

Nope! A PCM will take you through all the basic mods. If you do a cam or have to do injectors, etc you will need a cutom tune. You can drop all the pulleys you want but you'll do a lot better with a custom tune.
I agree with dsmuts on loading up than get a great tune.
