I have a d16z6, ihi rhb5 turbo(8lbs boost) hf mani and dsm side mount intercooler. What size fmu is required for this setup and will I need new injecters and fuel pump?? Thanxxx.

 

I cant say that any fmu would be your best bet as far as fuel managment but Ive put a 12:1 vortech on a z6 w/ a 14b turbo running 9lbs. of boost. you do not use bigger injectors with the fmu, though putting a walbro 190, or 255lph fuel pump in would be your best bet when using the fmu. the fmu will make your car run extremely rich . hope that helps. BTW you will also need a missing link to hide the boost press. from the ecu!!!!!

 

fmu's are really unreliable,
there I said it,
i'm sure you'll get enough people covering the fact that you shouldnt run an fmu, but rather uberdata or vafc hack

BUT if you do go the fmu route,
you definetley must get a fuel pump,
walbra intank is a good choice.

you dont need upgraded injectors, that will only eff up your idle.

10:1 or 12:1 are your choices, most ppl go with the 12:1 but I think its overkill,
you can run rich as **** with your 12:1 fmu and still be just as unreliable, cuz those thinks can konk out on you at random, and they're completely untuneable.

if it was me i'd run a 10:1, especially for 8lbs.
