File 2021-10-07 20_17_17 IJE0S IJE0S 91acn Pure Stg2 DD 3.5 v4 - WBAWB7C53AP049283.mhd_.csv
Added October 08, 2021 by IsoFLXX
Here 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.
