OK guys, ive been doing a little bit more research.

Now the injectors im going to use will be from a CA18DET (hoping they fit). 370cc, top feed, low imp. So i still need a resistor box. Now, since ill be scaling the AFC down lower than typical 450s, going to start around -25% -30%, does that mean i wont be able to run as much boost. since the AFC is scaled lower, would i throw a cel if i run like 8-9psi with -30%?

The reason behind using CA18DET injectors is quite simple. I know there are heaps to find in australia, going for a cheap price, & since i only plan to run under 200whp, should be quite adequate for my needs. 450 DSM injectors, i would need to buy overseas, counter in exchange rate & shipping, they end up costing me more, so sourcing injectors locally will save me alot of time & money. However, i cannot confirm for sure yet, Ive been told Mitsu Lancer GSR injectors are 450, but i have to confirm that...

what are you asking?

Ok, with 450s, -40% you can run about 10psi.
I wana know, with 370s, -30% across the board, can i still run 10psi (in actual fact i only want to run 9psi max) without throwing a code...
