you can drop sometimes .1-.2 pulleys izes. its not an exact math like that. more or less it will depend if you alreay have knock, and it will give you some head room. it usully drops boost a bit so thats the need to change pulley sizes.
zzp tested these and gained 16-18 hp from these only

it comes with a tog DP you will need a little work to make it all go together. good time to consider a highflow cat. will make it easier also to fab to it while these are getting installed
