your not damaging anything,but your just flooding the engine.wasting gas is all.theres no point in putting bigger injectors in if you dont run more boost and have some way to control them.
 
Ok my profile is pretty detailed but the main related components are:

16G Turbo
FMIC w/complete piping
Intake, DP, & Exhaust
RC550CC Injectors

I'm having a funky idle issue-I'm assuming that these new injectors are bogging my engine down with fuel-thus the odd idle. I did, however, just re-set my ecu-which does make your car run kinda choppy until it sets, right?

Ok, I've heard that all I need is a Air/Fuel controller & a 190LPH fuel pump and everything for this turbo will be fine and no FPR is required. I may upgrade to a large 16G in the future-but not for a while so I don't believe I need a 255lph fuel pump.

I was going to order the AutoAlchemy fuel line upgrade but the site is MIA. I guess I'll go with the SBR kit. Any advice as to what type of AFC I should purchase? Should I go with a GM MAF & MAFT? Is my bad idle due to the bigger injectors? I don't have the stock injectors since it was a trade so I don't have the option of throwin' in the stock ones until I do so. I NEED to drive my car since it's my only means of transportation right now-I'm running minimum boost and have my MAF screw backed out to the max. Am I destroying my engine by running these injectors w/no management? My gas mileage is the same (340-360mi/tank).
