Fuelling wouldn't cause air filter flutter noises.
More likely boost control related. Give the boost control solenoid a clean through with carb cleaner.
Are you running a 2-port or 3 port boost control solenoid.
Could be weather/temp related as the car will try and produce more boost in the cooler weather and the boost control may be a touch high, hence it gives a quick spike and the ECU is trying to get it back under control, hence is flutters/stutters.
As an aside, I hope your running a high pressure FPR if your pushing 352BHP on Yellows and maybe even a wideband AFR permanently installed.
