Stock Injector?
Stock Injector? 
Hey guys,
Long story short, I bought a 99 Camaro LS1 with a Procharger system on it. I removed the Procharger and got a factory tune put back on the PCM. Now I car seems to be dumping a crazy amount of fuel and has no power. If I punch the throttle the car revs to 2500 and falls on its face and won’t downshift. There is a large amount of black smoke coming from the exhaust as well. I am not familiar with this car as I just bought and the previous owner was very very unsure with what the car had. I believe these these injectors are stock but just want to confirm. Also would a colder burning spark plug (that I am assuming the previous owner put in) make this much of a difference? The cars been sitting for the summer so I guess the fuel could be old as well. Any tips or ideas? There’s no SES light on right now.
i believe the car is 100% stock now minus headers and air intake. The only thing that looks out of place is there is a small filter hooked up to the tube coming off the front passenger side valve cover. Not sure where this is actually suppose to go!

Sounds like the previous owner put larger injectors in to handle the increased demand for fuel the Procharger needed to feed the engine correctly. You put a stock tune in it which is intended for stock sized injectors, but with the larger injectors, it WILL run pig-rich! Put stock sized injectors back in and you should be fine.

Thanks!

I have some I'll never use if you want them for shipping cost. missing a couple orings though...they were a damn tight fit in an ls1 intake
