What is the difference in performance between the two(tuner and pro series)?

Which one would work best with a setup like; gsr block with itr piston supertech dual valve spring with flat valves? ex. tuner stage2 vs pro stage1, tuner stage2 vs pro stage2

Sorry for the newbish question but i tried doing some research and for some reason ended up stuck.

Thanks for any help

 

i assume you are talking about cams?
you will be better off going with the tuner stage2 the pro1 and pro2's and designed for higher compression motors or more built motors... pluse you'll most likely need different valve springs for the pro cams

i would try searching in the all motor sections... it has been done plenty of times before
