Now they have been selling them all along, and will have more in stock in a few days? As I said this is slightly confusing to me. But Im glad it worked out this way as now I have my own.
    I had them made some time ago, and have been out of stock for quite a while. I am getting a lot of requests for them, so I am having more made for stock.

    UPDATE: Pretty much nothing interesting, LOL. As a quick recap, I've been getting high RPM misfires on cylinder 6, so of course I did the routine coil, plug, inector/code which didn't help. Well last week I did a compression test AND leakdown test and everything looks good (insert sigh of relief). Also, the last time it happened I had a fuel code which has now popped up a few times, so I don't think it's a fluke. The next steps will be HPFP and valve cleaning (both of which need to be done regardless of the misfire). I haven't been able to get any further because the primary O2 sensor on bank 2 crapped out! On the BT scantool it's showing about 8 volts at idle, which is way too high. This is actually the second time the same sensor has crapped out since doing the turbo upgrade, so it looks like a heat issue. I don't think it's high EGT's, I think it's a matter of the sensor not being able to dissapate heat due to it's location. So far there have been no issues with the sensor on bank 1 (which sits up front ahead of the manifods/uppipe). Now I'm just waiting for that to come in, at which point I'll fab up either a heat sink or heat sheild to lower the radiant heat the sensor receives.Anyway, that's what's going on. I didn't want everyone to think I dropped off haha.

    Good luck man! I really like your set up now that I am in there and see how little room there is. Really nice job, I really think you were gonna have a hard time getting the O2's to live, they just aren't designed to take that kind of heat on a continuous basis. Keep us posted

    Are you MT? If so, the stock DMFW is known to misfire at high rpm and high hp.

    Thank you. I'll try to update the good AND the bad so people will know what doesn't work.

    Not sure which style O2 bung you are using but the AEM Finned Wideband bung might dissipate heat.

    Yep, that's the one I'm running. I was thinking about also running this in conjunction:

    @Eleventeen , looking over this setup again, how much clearance do you have up top from the turbo to the strut tower body of the car? Doesn't look like much is left there...Have you considered motor movement and the turbo housing hitting the body there when going WOT or bouncing from part to full load at higher boost? If you wouldn't mind possibly taking a pic of the space there I really wonder...maybe 1/4" left in between?

    I can get a picture. It's about 5/8" or so. The turbo blanket touches since it's pretty thick, but there's no metal to metal contact.

    Okay, I walnut blasted the valves today and ordered a new HPFP. The valves didn't look as bad as some of the other's I've seen on here and cylinder 6 wasn't any worse than the other cylinders; so I'm not confident it was contributing to the misfire. Regardless, it needed to be done.Click here to enlarge

    You should have took it to the dealer and asked for the HPFP recall work to be done just to see their faces, lol.

    Are you going to open up the inlet and outlet of the HPFP to see if this is the limitation?
