I would also like to know this about the retune....I have read about this upgrade... Still trying to grip it all...I know that the BPV on the Stillen unit just recirculates the excess boost back into the system versus changing out to the Turbosmart Dual BOV allows you to vent to atmosphere.....so the question I have Is it just cosmetic/aesthetic for sound, or does it improve performance over the bosch style By Pass Valve....There's been different opinions about this....I know a handful of guys have done it and recall Diego@Vossen citing that Kyle Millen even had this upgrade on his Black 370Z....but Stillen never really gave a clear answer on the performance aspect of the BPV vs BOV....
Do any of you have a pic of where this part goes when replacing the stillen unit?
