i am using the greddy blue box right now, but i am not using the 310cc greddy inj. i am using some rc 440cc inj, but now my car is running like hell, can i use the vortech fmu to smooth it out, all this is in a stock 99si with greddy turbo kit with ic and bov

the greddy blue box was designed only to be used with the 310cc injectors. why did you put 440's in? all and FMU does raise fuel pressure in accordance w/ boost...that will make your situation worse. you need something to control the larger injectors, like an AFC or that SMIC thing.

of course, what you relly need is a well-tuned standalone but i assume that is out of your price range right now?

i am using 440cc inj is because i was to use hondata s200 with boost, i got the money for that but since it comes with a blank chip, i got no money to get it tuned, freaking shop "freaking modacar" wants 250 an hour to dyno tune it, imo, freaking rip off, i just need to do something for right now until, i get $$$$ for tuning
