So do you or do you not have a turbo on your car right now?
If you do have a turbo on your car, and you have stock injectors, stock fuel pump then you are wasting your time. The stock injectors are not going to get you anywhere with boost.

Ok i will post logs and tunes when i get my couplings for my turbo thats all i need. Then thing i didnt understand on post 21 was the histogram part. i dnt think i have my histograms setup right i adjusted mt afr in closed loop but i was a lil confused with the data it gave out
You are going to need larger injectors for boots.
what i be able to do anything in the mean time i am low on money.
Your injector duty cycle is going to determine that, but not likely.
Stock injectors are close to be maxed out in stock form.
How do i increase my injectors? Right now the constancy is at 0.17800
Ok it will be awhile until im able to get injectors. I'm still waiting for my turbo to get finished
Ok so the turbo is connected i followed post 21 and i am about to do some logging
Ok so turbo is on only boosting 1 to 2 pounds something is wrong with my set up. I cant boost it any more. Either waste gate aint opening and closing, boost leak which i kinda skimmed through, Injectors, my manifold something. I feel a power difference but not a lot. But here are the tunes and logs.
Injectors will not limit boost.
Truly until you get bigger injectors and intercooler you shouldn't be building boost.
Yes, 60lb injectors work perfect on a 2.0 lsj with 25psi so I think those would be the biggest for you. 42's are the stg 2 lsj size and people run them to 20 psi on the 2.0 so if your only going to 8-12 psi the 42's would provide the fuel at wot and have better idle quality.
What about the 2.2 dohc i have a 2004 cavalier not to sure what the fuel pressure is.
Ok and just to ask for sure its the injectors thats not letting me boost right? I had the turbo connected at one shop adjusted my afr, and it still didnt work. So i took my car to another shop so they could re do the turbo install. The mechanic there keeps suggesting that it wouldnt be the injectors that the turbo is exhaust driven and that the wastegate controls the boost
Injectors will not stop it from creating boost.
However, without proper tune and injectors going into boost will cause engine failure.
Ok. Im still not boosting yet turbo install went bad at one shop so im taking it to another. Is there anything i could do in the mean time to get some hp wastegate, downpipe, everything is connected except charge piping have aem cold air connected
