I have been searching everywhere and reading any thread I could find to try and pin point this issue and I'm still not 100% sure what I'm dealing with. I would like to try and save myself from replacing every possibility before I finally resolve the problem on the 10th try, so hoping someone out there might have more of an exact solution. So, a couple weeks ago in my 2013 VT, I started noticing that when I apply enough throttle to start building boost (approaching 15 psi or so), the car essentially begins to stutter and hiccup. When I just drive normally without giving it too much gas, I can rev through the rpm's no issues. The car idles and runs completely normal otherwise. I believe I have eliminated the possibility of a fueling issue by running some data logs and numbers are exactly in the proper ranges. After ruling that out, my options are spark plugs, coils, ebcs, or boost leak. I checked the plugs and while they aren't brand new and appear to be the factory plugs (so I should plan to upgrade anyways, probably HKS), none of them were fouled out or were an obvious problem. I should note that there has been no check engine light and I also should note that the car is completely stock. My big suspicion is the ebcs as I have read about those being a common failure point, but I have not found if someone would experience the same issue as me if theirs had failed. Any further input would be much appreciated.
