    Really bad shudder

    I don't think relocating the MAF to after the BOV would solve the problem, because even when the car is not under boost it jerks. All it takes is being in the RPM range and just a little throttle. I guess I could try that though if the current round of stuff doesn't work. Right now it's in...

    Really bad shudder

    I would easily buy a ssafc if I knew that would solve the problem, but I don't know that it will and I don't want to spend $400 fishing for solutions. I'm a little frustrated atm, because undiagnosed problems are the worst. I've got it in the shop right now while my guys try to figure it...

    Really bad shudder

    SSAFC? What exactly does the reflash do? I haven't understood that yet. Thanks for your help. That's a really good point about the cold air intake and warming up the car. That's almost worth getting a stock airbox just to try that out. At this point I don't care about performance I just...

    Really bad shudder

    I've got a boost gauge, and it's saying that that side of it is fine. 6 psi at WOT, and 20 vacuum at idle. I've got an aftermarket exhaust with a generic cat, but it did this before when it was straight-piped with a different muffler so that can't be it. It doesn't matter which gear I'm in...

    Really bad shudder

    I've a '03 MSP that anywhere from jerks violently to shudders just a little, to no jerking or shuddering at all sometimes. It's always between 2500 and 3100 RPM, but sometimes only between 2900 and 3100 or so. It's not the WGA, it's not a vaccuum leak (had both tested at a shop), and no Check...

    I'm fairly certain it isn't based on the consistency. I'll put some Seafoam in the fuel, which I had meant to do before. The quote was for piping along with putting on the muffler and cat that I had.

    Any reason why I should be getting so much black crap on my bumper then? I know the MSP runs rich, but other than that I have no idea.

    It's going to be fabricated with me supplying the cat and the muffler. There's a reliable muffler place here that said he'd do the piping and put everything together for $150, with another $30 or so if I wanted a chrome tip. I do want a nice sounding muffler along with the performance, but the...

    Bump. No one?

    The owner before me replaced my MSP's stock exhaust with a straight-pipe no-cat exhaust with a flowmaster muffler. In addition to the extremely loud drone and exhaust note that I don't particularly like, the exhaust love to belch that black soot, which gets all over the rear bumper every time I...
