    I've always wondered what those do exactly, I've never owned a turbo car before, I hate being "that guy" but if you don't mind when you get a chance maybe help a fellow cruze owners out lol

    The car made much better results with the XR PCV kit installed (boost leak source was the stock PCV valve) and plugs gapped to 0.024". Unfortunately, my injectors are hitting 96-97% DC at 20.5 psi. WGDC is mid 90s as well...But still, 167whp/204wtq is just fine for me, especially on a dyno that's known to hurt feelings. And I'm happy to have gotten a 15.0 at the track too. It might not be as quick as a Malibu 2.0T or a 3.6 Impala but it's close enough for me. I ended up installing the green spring back in as well.

    Glad your problem got fixed, and that it wasn't a tuning issue!

    We can always push it harder if you wanted... But I'd recommend injectors before that. ~95% IDC is static on the stock injectors.
