Stage 2 (DINANTRONICS Performance Tuner in conjunction with Dinan Intake and Exhaust) Maximum Power: 384 HP, 417 lb-ft of torque.

In addition to increasing boost and optimizing the fuel and ignition data, the DinanTronics Power Module is tuned for the Dinan Intake and Dinan Exhaust on the N55 EWG. The Dinan tuner box plugs into the existing sockets on your engine computers The original wiring harness plugs into the Dinan tuner box. There is no cutting or splicing into wires and the whole harness is completely reversible at any time.

Because the DinanTronics module plugs directly into the engine computer, it can control the data from every sensor on the engine - not just the two or three that other piggyback-style modules use. Instead of only modifying a boost and RPM sensor, the Dinan power module sends a modified signal for fuel and ignition tables, target Lambda (AFR), exhaust temperature, knock sensors, and more. It has the ability to correct short term fuel trim and ignition timing errors so even as the boost increases through the whole RPM range the engine mapping remains where it should. Not only does it make a lot of peak power, but it's also a smooth and consistent power gain over the entire RPM band. The Dinan tuner module is the most sophisticated on the market and is the only one that is 50-state legal.

The engine computer(s) is part of the intake manifold so access is tight. The Dinan module is installed under the radiator support and the harness has to be run to each computer. Detailed instructions are included but professional installation is strongly advised if you're not used to working around your engine.

    Terrible pillows
    Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
    These pillows might be fine if you need them for a decorative sham, but definitely NOT to sleep on. They are super lumpy and soft, days after taking them out of package. It seems like there are just bunches of cotton strips in a row that are hard to fluff. They are also dark in some areas, so it looks like the pillow is stained, when in fact it's whatever material the stuffing is. I can't return them because they won't fit back in the box. Super disappointing.

    Comfortable from the first night
    Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
    I found them comfortable and with good support for the head and neck. They are wide in size and feel soft when lying down. After several days of use they continue to retain their shape without problem.

    Not as Firm as I had hoped
    Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
    A good pillow. However, there is quite a difference between the manufacturer's and my idea of "medium firmness". I found this pillow much softer than I had anticipated. I'll have to go for firmer for my next purchase.

    I admit when I was wrong.
    Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
    3/29/26 - I took the pillows and put them in my dryer on steam refresh for the default 10 minute cycle. OMG - they fluffed up and evened out to be soft and comfortable, no lumps whatsoever. If you like a soft pillow with some support, but not firm support, THIS is what you want. I am truly amazed. ================================================== Previous review---They arrived in a vacuum seal bag. When you cut the bag and they inflate, they inflate lumpy like. Some areas are thick and some have to fill so, not very good. I am going to try washing them and drying them to see if they fluff up better. Will post the results in a day or two.

    Immediate neck and back pain
    Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
    Nice full pillows that holds its shape, BUT was NOT good head and neck support. I noticed an immediate difference. From non existent to growing neck pain in the first night’s use, through the week.
