I own a 2008.5 MS3 with about 1900 miles on it. The only thing I have done is a Forge BPV, blitzdtt, and a set of street unit boost hoses a friend gave me.
I had the forge bpv installed since the car had 300mi and the boost hoses went on this last Saturday. Sunday I took the car for a drive on the freeway and noticed that in 6th doing about 70 if I got on the throttle the boost would spike to 1.30hkpa before settling down boost number I cannot be sure. I had the warning beep set at 1.30hkpa. I enjoy a slight boost in performance after the boost hose install just enough for me to notice.
Well the problem if any started Monday evening. On the way to the restaurant I decided to take a road that had couple curves into a long straight that ran along side the freeway did not get to crazy but had a little fun through the curves and a bit on the straight. I got the warning beeps a couple of times on the way to dinner. Now this is the weird part, after dinner I left the restaurant and got onto the freeway to head home. I noticed that the car was running a bit sluggish. So just to see I got up to around 70 in 6th and got on the gas and I saw that the boost only made it to about 1.20hkpa. I then down shifted into fifth and gave it some gas and kept an eye on the boost gauge and saw that I was building boost but the car just didn't seem to pull as much as it did the previous day or even earlier that evening. I figured ahh I must not have tighten the clamps down enough. Got home a rechecked all my work. All hose clamps are tight and secure. BPV is on correctly line for the boost gauge is on correctly. I am out of ideas as to what it might be.
Now here is what I am thinking:
Either something happened to the hoses or clamps or there is a leak that I am not seeing.
The ECU noticing that I am getting more boost and is correcting to keep it within spec.
It’s just me and I need to stop worrying.
I’ve been reading up on a few threads about blown motors and was getting a bit worried. My previous experience with boost was is my supercharged Maxima that I spent many hours wrenching on. So I do now my way a bit around a car. Any thoughts help are greatly appreciated.
