I have one on a 6.2 mercruiser running 7 psi of boost burned a hole in a piston after 40 hours running Procharger gave me very little help and basicly told me I did something wrong. If you go with procharger have the ecm reflashed also add a oil cooler and larger oil pan
go to website they will send alot of infomation on different setups
