If porting the stock SC, change the upper to 2.1 pulley would net you 14%. If not do the lower pulley 9.17.
I ported my SC and run dual meth with 2.3 upper and 9.17 lower. Added the upper bc of the better flow from the SC now and to maintain boost. Some would say that it’s too much and the SC will heat soak. I don’t run back to back as I like everything to cool down from Diff to trans so I don’t mind waiting 30-45min between runs.
