Good lord, 390s? My brother's car (4A-GZE) is using 365s and is running fine at around 10psi. How big is your engine?

If you use bigger injectors you'll need something to control the fuel dump. You'd probably run a bit rich if you just drop the injectors in.

The combo for injectors is normally "larger injectors + AFC || SMC"..

For 5 psi just run your stock innjectors and checkvalves.
It wil be enough for 5 psi did it a few times though.
And my engine didn't blow up.

For 5psi that is a bit overkill, the 390cc injectors are to way large for the stock ecu to controll, you will need a device to pulse them slower (afc/hack/smc/fields)

390's are a bit too much.
Possibly 310's?

Thats funnt I was going to run DSM 450s in my 1.5L civic, but now they are going in the Stealth R/T, I'll have some 360cc injectors avaliable after I put the R/T back together...
