srt-4 engine light overboost condition.

heres a list of my mods
e1 turbo
fm wastegate
dsp (of course) 9r16
walbro fuelpump
aem shortram
180 thermostat
maxxfab 3 inch o2 housing with a 3 inch downpipe no cat to a 3 inch side exit.
coldside pipe with hks ssqv
well i fianally got a wideband so i can raise the boost on this thing, i was hauling ass in 3rd shifted to fourth held 18-20psi, and around 5000 rpm it just started backfiring and nosedived like it ran out of fuel, my a/f was at 11.2 when this happened, then 30 seconds later my check engine light came on, i checked the code with the dsp and it said "supercharger/turbocharger overboost condition", is there anyway to prevent this from happening, someone said to disconnect the red line from my hard pipe and cap it off but doesnt the computer need to know how much boost its making

I'd post the last tune written here so we can take a look at it, overboost code should be disabled in the tunes.

The popping is likely overboost protection mode.
