Ok...I have 2011 5.0 with the Roush TVS, 85mm pulley, 47# injectors, stock Roush airbox. I also now have the 9.5 Aluminator I just put in. I want to go with the 79mm pulley. According to your website it states: 79MM pulley for Roush 2.3L TVS Supercharger kit on 2011+ 5.0L Mustang. Increases boost to ~10psi when stock enclosed airbox is used, +2.5 over stock. Supercharger kit comes from Roush with a 90MM pulley that makes 7-8psi. The smallest pulley you can run without needing fuel upgrades. May be used with pump gas. Black anodized aluminum. *Ti-VCT settings will change boost, quoted boost numbers based on VMP Tune. Just want to make sure I'm good to go with the 79mm pulley with my setup before I make purchase and will this require a tune adjustment? I'm running your VMP tune. Thanks guys.
