Blow off valve and compressor surge between tunes

Sounds like the tuner neglected to tend to a specific table or something.

Traditionally, these valves were operated via engine vacuum, simple mechanics. Like stated, the 13 plus 3.5 EBs (IIRC), are now electronically controlled. Presmably, controlled by ECU parameters, although I am ignorant to the exact control schematic.

Nothing new I guess. Couldn't find a solution so just letting it happen. My tuner (Torrie at Unleashed) has no solution either. Going to get hot pipes this summer so hopefully it'll help or even be the solution. Otherwise I'll have to rig up a mechanical blow off valve somewhere to prevent damage.
