Turbo noise

Definitely let us know! the z57 package comes with the remote tuning as well, but I haven't had time to pull the stock file (or even start the engine build) so I have no idea if I'll have that gobble noise or not (hopefully not). Out of curiosity, where do you have the bpv plumbed to?
Yes I haven’t never done this tuning stuff before, So it definitely takes me awhile to figure this stuff out. I can send you a copy of my latest tune from them with a conservative boost to start with I didn’t want to blow the head gasket again on a new engine with 700 miles on it. That was a pain undoing everything to get engine out.

I don't blame you for avoiding the blown head gasket. I wish there was a better replacement than the stock GM part. I'm going to be running head studs so hopefully it will get a good clamp around everything and hold it all in place >.< Have you tried switching the fitting that the brown bpv connects to? Moving it to that side post that's open I mean in your last picture.

See this thread for reference pic of the bypass solenoid configuration.

Yes I used head studs this time , I was shorted a nut and didn’t realize until I went to install so had to wait 2 days for bolt to be delivered

According to AZMoto’s link, you have the bpv hose connected to the wrong port. Look over that picture and compare it to your setup. Might fix the gobble.

@Zoom Zoom That port on the solenoid is open on the zfr turbos, it's a vent.

Yes that’s what ZZPERFORMANCE said also to leave it open.

I'm happy to look at your logs and work with you on the tune and a baseline. Check out the tuning section below and feel free to start a Tune diary of sorts and I/we can help you out


Before you go back and forth with ZZP, make sure your fuel trims are dialed. It's impossible for them to tune your vehicle with trims misaligned.

This is the answer ZZPERFORMANCE sent after I sent pictures of the way I had the lines routed , He didn’t say anything about them being wrong

Weird so they don't want that last open port on that solenoid to go to the nipple on the side of the Z54/57? The round tanish plastic piece?

OK I took the Goblin out for it's first scan but before I went I reversed the vacuum lines and THE GOBLIN STILL GOBBLES :) But I did find out the vacuum cannister is working because it definitely made a vacuum sound when i unplugged it and that's after sitting all night. This thing only gobbles when you left off of gas. :eek:
