So, i have an A4 LS1 trans am.. it had check engine lights on.. and when i put the reader on it, it read either cats or rear o2's.. I had all of that tuned out so i would pass inspection as well as evap i believe and EGR. My car was stalling at wide open throttle before any of that anyway. It's still doing it.. i can leave it in first and mash it and it will stall.. or i can be in drive and race from a dig.. and when it shifts it seems is when it stalls.. or mash it at 70 and still manage to stall it..I'm not sure if its really a stall though because the tach just drops off to nothing and the car completely shuts off as if its just dead. I've cleaned the MAF.. replaced my fuel filter.. I'm having headers, ORY, plugs and wires installed in 2 weeks and a FULL tune done.. but I don't think its the plugs because there is no backfire.. it just dies out and completely shuts off the car. What other problems could I be looking at? sensors, leaks anything guys really need some help here, im baffled and it sucks

clogged CATS will cause this.

that would be nice if that was the problem

Have you checked your fuel pressure to rule out the fuel pump. Also if that doesnt work could be a crappy tune and i would take it back to your tuner.

hasn't been tuned yet.. and i stalled it today and heard some weird clicking.. almost sounded like piston slap as it was dying/stalling out.. but when is tarted it back up everything sounded 100% fine.. im baffled
