Intake/turbo stutter after IE intake install

[Yello_s3]

Hi guys,

Ever since I upgraded from OEM to the IE turbo inlet & intake I’ve been having these annoying stutters coming from either the intake or inlet connections. I have double and quadruple checked all hoses and connections and everything is installed properly.
The stutter starts at higher rpms and especially when flooring it or doing pulls which just feels terrible and also is obviously not supposed to happen.
I messaged IE back and forth and they were absolutely useless, said that it was normal or caused by whatever tune the car has.
If anyone can help I’d greatly appreciate it 🙏

Is it happening right when you let off the gas pedal after doing a pull? If so, that is normal and is supposed to happen. You are hearing your blowoff valve more since you are taking in more air than the engine is used to. If not, there may be a bigger issue.
