Default blower got crazy loud

I just recentley installed a set of 60lb injectors and had my computer retuned, and I dont know if its just me or if my blower got way louder but after I installed the injectors I fired it up just to make sure everything was good to go and it seemed twice as loud idling as it did before, anything I should check?

O, mods are d1sc, 8lbs of boost, fmic, 60lb injectors, long tubes, ory, hooker cat back, tea 1.5 heads, ls6 intake..I have the vortech bybass valve.

a blower just doesn't get louder for the hell of it. make sure it's not bearing noise.

i've got an idea... you need stronger pistons... lean out your fuel on stock pistons and you'll end up with a hole in them. saw that problem on a 05 dodge with a cummins tdi. if you want pics tell me, but otherwise i don't feel like looking for them. back to the topic, is your engine running rough, or just the increase in noise?

another idea... its just human to feel like something is going wrong after you install anything, even if everything's fine. you just feel like you've messed something up any time you make a serious change to your fuel system, or anything for that matter.

check the intake hat on the blower or if any of the pipes blew off , that usually makes the blower noise more pronounced.

If some piping is leaking off air that is mostly like it, mine sounds awesome when it blows piping off, it just makes 5psi when it does, lol.

I'm interested in what you find on this, my P1SC has been loud as **** from day 1 but is still running strong 15k miles later...

One day when I find a pile of money sitting around I may send it in for service.

I checked last night I didnt find any leaks, its seemed all the noise is coming directly from the bypass valve, it might be all in my head and that I havent drove the car in a few months...
