Hks bov issues
Hey everyone. I posted about this issue before on another topic but got no response. I'm hoping I get some help from here.
So here's my problem: I took my car into the dealers because of a high pressure fuel pump recall and they also had to do a software upgrade as well. Keep in mind I had the hks bov installed before taking my car in and it was working fine. After i get my car back my bov performing the same. Now I have to rev pretty high Rpms in order to get a little sound out of it where before it would blow off at low Rpms. Also when I'm at wot it hesitates to blow off. Any ideas? |

One thing you can try is to rev or drive immediately after a cold start and see if you hear it during low rpms.
With the new software, I have noticed the wastegate position is changed around 30 seconds to a minute after cold start. |

I'm having a hard time justifying the software affecting my bov. As for the Rpms I have to take it to about 5-6k. I used to be able to hear it go off around 3-4k. But also when I go to wot around 7-8k rpm it hesitates to blow off.

+1 on the synapse! But seriously, I believe it may be the update. I installed my ER CP w/ Synapse BOV after my HPFP replacement about two weeks ago. In order to hear the BOV, I have to take it up to 3500 + RPM to hear it. My friend has a AA BOV kit and I can hear his at 2000+ RPM! He has not had the HPFP replacement & software update. I wish I would have had my BOV kit installed before the update then I could answer your question efficiently.

I'm not running a tune, but my friend with the AA Bov kit is running JB3/Map 3. Hmmmm, I may have answered my own question!
