can someone tell me where i can buy a used Vortech FMU and how reliable a used fmu is? also, where can i get a used missing link? and what should i expect to pay for both used? and what are the negatives of running a 10:1 vortech fmu plus missing link over the greddy blue box? <<edit>> im still @ 5.5psi, but as soon as the ic i ordered comes in (along with a weekend of free time) im going to turn the boost back up to 10psi... will a 10:1 fmu suffice @ 10psi?
