I have a supercharged VT Calais and it has a twin 2 and a half CAT back I was going to get the 10psi pulley kit but I'm wanting more, so my question is if I brought the 25mm manifold spacer could I run more then 10psi without having to get a W2A or A2A i

If you were to purchase our L67 manifold insulator kit and have it ported along with the manifold and supercharger outlet (supercharger not necessary but beneficial), you could run an 11 psi pulley without intercooling or a custom tune. In saying this though, we would recommend considering working towards our budget package as shown in the link below
