Straberry, Turf, and goatsmilk?
What's the difference?
A better description please.
Sounds like you might be talking about Nitrous?

This link has a decent description of the two injector types:

If you are currently using saturated injectors (most likely), it would be easiest to stick with those. You can use peak and hold injectors, but you'd need to wire in a resistor box.

ok well i'm putting 18 lbs to my built D16 eventually and the only missing link is the injectors... everyone reccomended RC 550cc injectors but they ask which i'd like. and i have no clue.

Re: Saturated or Hold and Peak? (Vaw7er)
Regular injectors should be fine. Just upgrade to an adjustable Fuel pressure regulator and bigger injectors.
You could really go either route, but regular larger injectors are more common.

Yes, stick with saturated injectors, but I would suggest more than a simple adjustable fuel pressure regulator as far as fuel management is concerned.

Yeah i've already chipped my P28 and i'm probably tuning with chrome... but i've heard alot about Neptune and a buddy said he tuned with it and ith's totally worth it. but i can't really afford another $400

Neptune does seem like a good platform, but if you already have a chipped ECU, you'll be able to get excellent results with a free application such as the two mentioned above.

You'll need a boost controller for that. Though I'm not too sure on how changing boost all the time works, because differen't levels of boost usually require differen't kinds of tuning.
Sounds like you need a daily driver to go along with your weekend/track car.
An 18psi daily is harsh man.

Re: Saturated or Hold and Peak? (ek forever guy)
I have my ecu chipped so that i can switch it between my 2 tuning styles... i have it set for 12psi and no nos at all.... and the 2nd level is set for 18 psi and whatever i do with spray. 
pretty sweet huh? just have to shut the car off, switch it, and fire it back up.

you dont have to do that. if the tuner is good he'll tune for the highest amount of boost you'll be running and everything below that. when you switch boost levels the ecu will compensate to match from readings from the sensors. i hope you realize to run anything over 11psi you'll need a 2.5 or 3 bar map sensor.
