Hi everyone, this is my first time posting so please take it easy on me. Let me start from the beginning. Around six months ago I installed the bootmod3 stage one tune of my car. The car ran beautifully for about two months before my charge pipe blew. I then purchased a VRSF charge pipe and had my local shop in San Antonio install it. Once I got the car back I noticed that the car seem to exhibit some throttle lag as well as a overall power dip compared to how it felt pre cherge pipe explosion. I then began thinking about what could’ve gone wrong. I assumed that since the issue happened right after the charge pipe was installed that it must’ve been due to the charge pipe. I brought it back to the shop and they did a boost leak check a.k.a. smoke test and told me that there weren’t any leaks. They even took the time to reinstall the charge pipe just for good measure. I picked it up today and the issue had not resolved itself. I then began thinking of other things that could be causing the symptoms I described above. I thought hey maybe it’s the tune. I then opened up my boot mode app and saw that there was an update around New Year’s that fixed the issue I seem to be experiencing. It dealt with sluggish acceleration at lower p.m. Unfortunately I am already running in the most up-to-date version of the tune so this seems unlikely to be the issue. I talked to a few friends Of mine, one of them told me that maybe it’s my recirculation valve. Another is still adamant that there is a boost leak somewhere. What do you guys think could be the issue? I haven’t been able to do a wide open throttle Data log for the car but I was able to gather some city driving and I noticed that my actual boost was over shooting my Target boost nearly everywhere on the RPM range. I would appreciate any feedback you all can offer me thank you for taking the time to read this.

And what about the O-rings ? Did they re-locate it to the new VRSF charge pipe and re-tightened the meth bung plug?
