Got it back from being rebuilt, ran fine for 2 weeks or about 200 miles of break in and she starts stuttering/missing. about mid way through the video you get a clear shot and sound of the miss. Went to go for a drive one night all was good as it had been then the next morning I go to drive and it's doing all that I mentioned. Cant drive now. Mods, e85, gt28rs, pbm HMIC, new oem iacv, q45 maf, pfc w/no controller etc.

Also replaced cts with a new oem.

You might have blown a coupler off or opened something with some spirited driving... Created a boost leak and causing it to run like hell

Fresh rebuild, sounds like something worked loose. Go back over all couplers, etc. Make sure all electrical connectors are clipped in and tight.

I'll look over all the piping, and grab some plugs while I'm at it. Also realized I never posted the video.

i hate the video orientation!
Anyway sounds like CTS the rhythmic rpm kinda confirms it at the end but its still a guess becausee it wasn't long enough for me to verify.
so if you don't find a major boost leak try that, cts!

Sorry for video quality, I already replaced the CTS (new oem nissan) when this started because that's what i thought it was initially. No boost leaks, anyways its going back down to the builder/tuner for him to warranty any work that needs to be done. Ill let you all know what the issue is as soon as he figures it out. Thanks.
