on my 93 wrx there is a 'field sf-hbc simple fuel hyper boost controler' problem is i havent got no instruction manual for it i see it gives rpm kph splittimes etc and dont understand the boost settings, well actually i dont understand none of it really when it comes to setting it up, all i got was a lumpy idle, it has 3 memory settings and a boost sp setting,does anybody have this controller or where i would be able to get an instruction manual, done a search on google etc but nothing, sorry im new to turbo engines,
