ok, what is the differance between step 1, 2....

what duration will keep the torque down low but help alot on top.
i have a s14 sr if that helps.
i want to keep the stock turbo.
i have greddy fmic, turbo back exhaust for power mods.

i want about 300whp.

you more experianced SR tuners please give me an idea of what parts match a daily drivin car.
