Need 4afte Advise Options

[Celica90st]

hey i have a 4afte, and im running around 7 psi.. today im going to the shop to get the intercooler piping done and exhaust connected up, now i have a fpr on there but i am looking for a fmu, because im running such low of a boost is that a good idea? also would the 4ag injectors fit in there just to upp the fueling a little? and also does anyone have any vids of a 4afte or 7afte in action because there was 2 posted but they didnt work..

The adjustable FPR isn't really the right thing to use... Hmmm.... actually, using an adjustable FPR and using larger injectors have basically the same effect. So you can either:

Use an FMU

or

Use an adjustable FPR or larger injectors AND a piggyback like e-manage. (Preferred)

Since you already have the adjustable FPR, I would go with the piggyback. Then you want to boost the pressure to add fuel across the board (don't go higher than 70 psi), and then use the piggyback to lean it out as you need to via the airflow signal (map sensor) where you need too. As long as the higher pressure gives you the fuel you need, then you won't need to get larger injectors.

Also make sure you upgrade your fuel pump.
