turbo flutter and higher boost spikes
i recently got tuned with trifecta not realizing i said i had gms1 sensors which i dont and i think it caused me some problems. for the past day ive been trying to flash to stock and it seemed like it wasnt flashing i had a few codes P0036 and P2227 today i managed to get it to do a force full flash it made the car drive a bit normal.
at this moment i didnt drive much so there is no cels but i currently have loud turbo flutter and my car is boost spiking around 120-125kpa i think 100kpa is stock?
if anyone has any suggestions on what i could try and do it would be great
wot support says vince is going to write me a tune without gms1 sensors i hope its today and i hope it fixes everything

so i just went for another drive i now have the cel P2227 again
also the flutter only happens when i let the gas off, shifting etc at lower boost its more quiet and higher boost its alot louder my car isnt in limp mode it still boosts over 5psi but it will boost more then it should around 120 kpa

I have the exact same problem.
I had trifecta dual tune 24 psi put on 2 years ago and was working fine.
then i had stock tune put back on last autumn and the p2227 + flutter started the next day.
i lived with that for the winter and last week I put my trifecta tune back on the car. the flutter and p2227 went away the first time I took the car after the tune but came back right the second time i started the car.
i bought the car used so i'm not sure if i have the gms1 but the guy told me he had put a tune not sure if it was GMS1.
anyone have a clue of what could be the problem ? i'm almost sure it's related to a tune or a setting because it went away just after i put my trifecta back last week but came back right after.
thank you !

i got the car reflashed with the trifecta for GMS1 and same thing happened. Everything was working great the first run then when I got back from work like 4 hours after the flutter sound was back and soon after the check engine P2227 also.
Here's a video of the sound the car make :
