What Size??

if i have a T25 turbo w/ SMIC but soon swapping to FMIC...and didnt pay for a SAFC..what FMU ratio would I use for the T25 at about 10-13psi on stock injectors?? What is an 8:1 FMU good to?? its on a KA24DET setup

ill be using the SR injectors when I can afford the SAFC after a month or so...but need something now to boost on like 7-9psi if its safe on a FMU..let me know. thanks.

if i were you, i would limit myself to 7psi on the t25 with stock injectors with an 8:1 FMU.

you CAN use SR injectors but you will need a hacked MAF or SAFC2 to control them or your ECU will think they are stock injectors and you will run ULTRA rich!

i used to use an 8:1 fmu at 9psi with my old to4b turbo. did this for a few months, but never had it on a wideband

i wouldnt go past even 9psi with an fmu. its just way too much fuel pressure to be running through the lines and injectors
