lol, it just rubbed me the wrong way. Hopefully ill get some time to play with the car this weekend. I would like to wait for the boost tubes from Sasha before tweaking with the tune. I was thinking of pulling the bottom of the tubes off the intercooler and just letting it suck air like it otherwise would and see if its the restriction causing these issues.

Its clear to everyone that its bouncing. Which means that the natural frequency of the O2s to switch from rich to lean is getting close to to natural frequency of the intake system. I suspect thats whats happening. That would cause the hunt, and if we tap back in the crankcase pressure lines with a PCV valve (to protect the bottom end under boost) this would allow the system to operate at a vacuum and change the natural frequency of the system.

One way to find out, lol it just involves tapping into my boost tubes, but hey if im getting new ones anyways I might as well give it a shot.
