Hey, whats up guys? I'm having some issues with a 06 Chevy LSJ. First off the car is running insanely lean i can barely move it around in the driveway let alone drive it down the street. When it is running it almost sounds like it camed. I tested the fuel pressure. With the car off but the with the pump primed it starts at 50psi and very slowly drops. With the car on it hold at 60psi. It is tuned by ZZP but i have put the stock tune back on and its continuing the same BS. I tried replacing the MAF as well nothing changed. So at this point I need to swap out injectors or the Ecu. Before I try something like that, has anyone else been through this? Any information will be of great help.

Thanks Everyone

 

i was searching for something when i stumbled across your post.... retune is all you need. this is not a 70's charger so being lean isn't going to be down on 2 things.


super old post btw. and i know...
