5th Injector V.S FWD cpu & 40 pound injectors

[devin187]

I've gone to donovan's garage and checked out both, and installing the cpu and the 40 pound injectors is so easy to do , compared to the 5th injector, But what i really want to know is which makes the more HP, any one who has , or has owned a car with this upgrades who can tell me anything , wud begreatly appreciated before i go spend my money on either of them

In my opinion its better to get the ECU,

I don't think you will find anybody makeing more power on a 5th injectore than on a custom cal. The hole point of the 5th injector is to be able to turn up the boost cheeply.

yep, the 5th injector thing is the "cheap hack" method, and its results vary. going the 3 bar map and +40s with custom cal method is the *right* way.

Maybe someone can give me some advice.... I have an 87 Pacifica T1 that I am having the log intake modded to intercool. I have the boost turned up to about 12psi right now with an aftermarket boost controller, but was wondering if I need to up the injectors when I intercool it? I was planning to send my computer to FWDperformance to rework it for all the go fast goodies they do to it.
