You are running pig rich. What exactly are you using to tune the fuel trim?

 

[osnoozeo]

i have nothing for fuel cept stock stuff that was in, i have fuel guage but it doesnt work no more, i just havnt fixed that, while ive been trying to finish up the engine

You need some way to control the bigger injector's...MAFT with GM more than likley with that size injector

can i just put my old injectors back in for now, and will that solve this problem?

With no Fuel managment, You are doing nuthing but hurting your performance. Put your stock injectors back in untill you get some way of Tuning, And turn your boost down to avoid Fuel cut.
And by the looks of your profile, I dont know how you have not been dealing with Fuel cut already and or blown that engine.
I would highly suggest you Immediatly buy Some sort of Fuel managment system. And if I recall correctly Nuthing but DSMlink, AEM, Haltech or megasquirt are your options, Due to your current injector size.

You have gone completly assbackwards when it comes to modding these cars.. A FM unit should have been first or second mod you did.

Take a peek at your ECU, Find out if its Eprom or not. How to Tell Eprom ECU. If You are lucky enough to have one, Buy DSMlink and a Wideband Immediatly. There are Tons of vendors here selling widebands, With prices ranging from $160 to 300+

well allmost all the mods in the car is the way i bought it like a yr ago, ive done a few things, but most was allready done, i will look into it fuel management, any suggestions on one that is reasonable in price and a place to get one.

Good choice. You will be happy with your choice. Just keep in mind that you will also need an A/F Gauge like DougR said, better fuel pump and an AFPR before you go rampantly boosting.
