needing injectors, questionSSSS

american_muscle · April 21st, 2010, 09:57 PM

Hea, the time has come and my head and cam swap has finally caught up with meand my car seems to be running a little lean (starts up rough and dosent run QUIT like it had). Weird thing is that is doing it now....back in the winter months it ran fine/awesome. Change in weather have anything to do with it? Anyway, I am going to upgrade my injectors and am to NOT upgrade too much, was thinking about 24 lbs'ers. Here are some questions I NEED answered:
1) The car has PINK toped injectors with the letter D on them, are they 19 lbs?

2) If I change the injectors will I have to change the MAS as well? I have a granetelli 95mm calibrated for 19lbs....will the computer recalibrate the air/fuel mix?

3) Will I need a bigger pump, or just a bigger regulator?

I know I am forgetting something..... Anyway. Tell me what yall think, thanks!!!

I doubt you need new injectors but anything is possible. Did you get it retuned after the heads and cams? If not thats why its running lean.
