how much fuel do i need if i wanna run 7psi...is a fuel riser good enough or should i use vovle injectors 300cfm??/

chipped ecu or afc +injectors would be best ... fmu would work but not very good and its not safe at that high of boost

i have a chipped ecu, it has no rev limiter and it has a mugen program...don t know if that chip is any good for boost though...and how high(psi) would a fmu be good for??

SEARCH owns you noob, you have a serious amount of research to do before you go slapping a turbo on your ride, the way your talking the motor will be toast after an hour boosted, if you even think about running boost on the ecu with the mugen program....KABOOOM! you cant just throw bigger injectors in with out having a way to controll them, hence an afc or chiped ecu,(with removable eprom and software to tune it like turboedit,uberdata etc.) if you dont want to try to figure all this ---- out about chipping and tuning the ecu, cuz its a lot of work, just replace that mugen chipped ecu with a STOCK ecu, and use an fmu, i might get flamed for saying that, but not eveyone wants the time/mental investment in using a rom editor, if you run 7 psi on a smaller turbo with a stock ecu and an fmu your motor will not blow up because of fuel managment, thats my opinion, cuz its been done thousands of times...

thanx ..btw im using the ihi turbo from a t-bird..im pretty sure the internal waste gate is set at 7psi...i got my whole setup installed already just need the make a downpipe. another thing stock honda injectors are peak and hold right??..and so are the volvos, so i was told that i can clip in those injectors and use them without an afc only so i dont stress the stock injectors with the fmu..but stock ecu with an fmu sounds alright for now and it has a rev limiter isnt that dangerous runnin boost cuz if u hit limiter it cuts out ur fuel and under boost and....BOOOM??
