What size are these injectors?

[IronCityTurbo6]

The injectors on my GN have a blue stripe, and have this serial number:01D030B
I was told they are "009"s but there is some confusion about the blue stripe. I was told 009s have a green stripe. Also, I'd like to see some opinions about how much fuel pressure and boost I should be running. I have the injectors stated above, TA-49, 3" intake pipe, 3" Kirban down pipe w/Hooker test pipe and Hooker cat-back, stock intercooler. Every thing is stock except 17" Torque Thrust II's with 315/35/17 Nitto Extreme Drag radials. Thanks in advance

Look on the other side of the inj. Should be another number there...

What octane level are you running? How much timing? For pump gas you should be ok around 17 - 18 psi properly tuned.

I forgot to mention. There is another number on the injectors: 1955. I am running a Turbo Tweak chip, 93 Octane, I just found for the recipt for the chip and it reads:

Invoice number: 1045
Date: 10-29-05
42 psi street 93
20*/18* 16-17 psi


Is the the adjustable variety that TT sells? I apalogize for the ignorance, but I bought the car with this stuff already on it, so I'm trying to learn as much as i can. I was at my local Turbo Buick meeting and some guys saw my injectors and think they are 36 pounders. I want to make sure the guy I bought my car off of didn't make a mistake and get the wrong injectors. It was supposed to have the 42 pounders.

Right now the car is running 93 octane with 19-20 pounds of boost with 60 psi of fuel pressure at WOT. I have seen a very small amount of knock, 1.7 degrees at it highest, and that was only once or twice. I of course got out of the gas when I saw this on the scanmaster.

So once again the injectors have the number 01D30B and 1955 stamped on them with a blue stripe. I have done some research myself and found a pic these: Racetronix-Delphi_Injector_Sale-42s
Which injectors are these?

That is the new number for 009's. They are 42.5.
