Was taking a thorough look through the bay of my S4 and found yet another issue. I noticed that the HPFP housing was slightly leaking and I’m planning on getting it looked at but assuming it’s just the seal gone bad. I’ve been looking into making more power but have been holding off on getting tuned until the time is right. I was curious if an autotech HPFP upgrade is a smart idea considering I need to take it apart anyway and wasn’t sure if it is at all worth it untuned or would even be compatible. Lmk if any of you have any insight or experience with a HPFP upgrade. Thanks!
