I'm posting this here because I think it might be tune related.

I built and installed a 408 in my CTS-V, and it started, but wouldn't idle at all, but with some throttle persuasion, it stayed alive. The car went through a drastic change:

Previous: LS6, 243/238 MS3 Cam, LS6 intake, PRC stage 2.5 heads, stock ls6 injectors

Now: 408 LQ9, 248/252 TSP Giant Cam, FAST 102 intake (and ls2 TB), same PRC heads, Deka 60# injectors

I installed a catch can, and here's how it's run:



valve cover goes straight to a grommet and nipple installed in the LS6 intake tube.

Valley cover goes into the catch can, then into the inlet on the side of the TB.

I thought the oil was full of gas, so I pulled the fuse for my fuel pump, cranked it a few times, and drained the oil, and yep, it was loaded up with fuel. REEKED.

So, after all this information, do you guys think it's tune related?

Did you change the injector data in your tune for the 60# injectors?

Valve cover goes to the tb port (fresh air). The valley cover goes to the top port on the catch can and the lower port on the catch can goes to the nipple on ur fast intake.
