no.. the reason ppl do this is to lower them compression ratio, but forged pistons for boost will have recesses in the crown to lower the compression
some ppl do run high comp forged pistons and still use a decomp to get the right CR...but thats not often and only if they NEED pistons quick or if they find a high comp set cheap..
or if they built a high comp engine for bodies etc..then decide to go turbo/supercharger later
