You really need to run an adjustable fuel pressure regulator with the wally 255.

would that fix the problem im having

Perhaps an intercooler pipe blew off? Did you check the IC system?

This, and turn your Boost down!!! Set it at no more than 15psi.. ideally at 11-13 until you get bigger injectors.

why would you even turn the boost without tunning first??

Running more than 10 PSI on a 16g is a really bad idea. You might be able to get away with 11 with no problem on a small 16g but honestly. I wouldn't push it.

I also agree you might have blown intercooler couplers. I'd check those, but when those pop off they usually sound more like an explosion. Kind of like a tire blowing out.

If that did happen the reason your car wouldn't die with your foot on the gas is you are giving it vacuum pressure where as when you let off it loses pressure then stalls and dies.

Boost leak test time.

Running 16psi on a TD05H turbine shouldn't hurt the engine unless there's something else wrong, but don't just take it as gospel. Use a datalogger.

Check for boost leaks those can cause a high pitched sound and also check the vacuum lines.
