lol fmu is a pos imo. i bumps up flue pressure with boost . but so will a flue pressure regulator. u can find a used kit cheap but , heads cam and nitrous is a nice set up. the 2000 kit has the smallest compressor you will max it out around 500 whp. now if i spend 2000 i expect to expand as my motor will take it . just my .o2 p.s. heads/ cam is the smart money imo
