Tunes and issues tuner specific

[EyeluvSmegma]

Mostly I'm trying to find out what tune you guys have gone with and what issues seem to most specific with each tuner. I'm tuned and I'm having a boost cut issue. Logged and sent, but still having that issue after updates.
Also, what PSI are you tuned for?
Really curious to see if ZZP tu ed guys are having a boost cut issue. From what I've seen it doesn't seem to be a ZZP issue.

What do you mean exactly by boost cut?

What do you mean exactly by boost cut?

21 psi to 5-7 psi max under WOT.

Interesting. What other mods do you have currently? Im having a boost related issue but not a full boost cut like this.

On this Sonic I have ZZP straight exhaust from turbo back, KN intake, BNR tune, ZZP springs, Bypass Bypass, BNR wastegste actuator, Forge BPV, DDM Works silicone charge pipes, Garrett FMIC, 25 shot N20, BNR ported throttle body, BNR TB spacer. Cruze PCV fix, DDM works coolant hose kit. Short throw shifter, shifter bushings. That's it for drivetrain I believe.

"This sonic" that's goals! Hmmmm you've replaced most all the problem areas on it I would think. I'm wondering if its a fuel related issue? Maybe not enough pump or something? If I'm not mistaken lack of fuel especially at WOT can cause fuel cut/boost cut. It sounds like you're making good boost at first and then its falling off, is that right?

Yeah, I think I'm going a different route with tuning. And I've just ordered a AEM pump. I'll put a fuel cell in the hatch after it comes in. I know there's mixed feelings about Water/Meth but I ordered the kit from ZZP today as well. Looking at Cry-02 for the FMIC as well. Not serious about that, but it looks interesting.

Only tune i think would be better is a one off tune if you know a good tuner? Have you taken this thing to the track? I'd be curious to see what kind of numbers it was putting down. I haven't gone water/meth yet but its something I'm looking into now that i have extra ports on the intake. I'm definitely curious to see how the set up looks with the fuel cell and water/meth in the hatch!
