I have a 93 civic w/ the greddy turbo, spearco i/c, greddy bov, walbro 255lph fuel pump and i'm using the blue box right now. The car is boosting to 6psi and i want to raise it to 8 using a profec B. Can i just increase it w/ my setup or will i need any additional parts(Fuel Managment..etc) Thanks

 

you should be able to go 8 fine. Anymore i think you would need to ditchthe blue box go with fmu setup. or even better get hondata.

 

thanks. I just have to change the head gasket and i'll crank it up. BTW when you hook up the profec b. if you turn it off will it return to stock boost?
