 Low Throttle BOV OscillationHere is a log of the issue occurring. Started log at beginning of sound. BOV continues to make oscillation or woosh sound on constant low throttle acceleration until pedal is released. Issues began after upgrading to pure stage 2 turbos and adding 2" inlets. Issue was not present with stock turbos and 1.75" inlets, not sure if this makes a difference.
*Update: Attached a GoPro in my engine bay and realized its not the BOV, rather the BOV type sound is coming from the inlets and DCI.
Mods: Pure stage 2 DD turbos, Tial 50mm BOV with 6psi black spring and shim, VRSF inlets/outlets and charge pipe, BMS DCI, VRSF 5" IC, NGK 97506 (0.22 gap), Precision race works stage 2.5 fuel pump (Walbro 295), Custom Tune by WedgePerformance, XHP stage 3 custom tune by SutphinTuning.

e30 mix Pure Stage 2 DD New logs Noticed some kick down when trying to log so i made sure to be in 3rd this time at the the start of logging. No sliding or traction issues this time around. Very responsive on the top end.

V3 This map is definitely more responsive and smooth throughout the powerband. This is definitely becoming a beast just on pump gas.

Version 2 I replaced the HPFP as advised but engine feels hesitant and seems to lag then take off. During WOT mid power-band seems a bit rough too and noticed this sort of pause, i then replaced the LPFP in hopes to fix this situation which seems to run a bit better but not 100% the solution. The new stage 2.5 LPFP is a Walbro F90000295 (535lph). Low throttle oscillation is also present when cruising in city limits not sure exactly what is going on at this point.
