VMP '10 Mustang GT w/ Roush M90 Stage 1 Power Pack - 2.49" pulley, idler, SCT X4 and Custom Tuning The 2010 Roush M90 Mustangs get a better intake from the factory, there is no need to change it. They also use a new press-fit style pulley - for this, we recommend our Ultimate Pulley Removal and Installation Tool. ( VMP-SUA031) Package Includes: VMP 2.49" press-on supercharger pulley90mm idler pulleySCT X4 tuning device(1) 91 or 93 octane tune file - We highly recommend the use of the VMP Ultimate Pulley Removal and Installation tool. It is a specialized tool made specifically for this job, most Ford dealers and mechanics will not normally have such a tool. They may have other tools that will work, but the time spent and the damage caused is often not worth the trouble. Our tool is designed to take the stock pulley off without damaging it, and allows for easy installation of the new pulley. Our installation tool uses a large bearing to allow the new pulley to be installed on center and with relative ease (due to lack of friction). No heat is required when using our tool. We can not guarantee the installation of our pulley when other tools are used.
