    Speaker upgrade 21 ST

    Keeping the stock amp and swapping in some nice expensive speakers will likely only make your system sound worse. The factory amp/DSP was set up for the factory speakers, so everything is tuned and balanced around them. Even though the stock speakers are nothing special, the system is...

    Loss Of Power But No Codes

    A similar thing happened to me on the way home from work about a month back. I assumed the turbos were completely down based on how it was driving. No CEL, not sure about codes. Next trip the power was fully restored, so I never hooked up a code reader. No problems since. I thought maybe it...

    Stealth Subwoofer Box

    Nice job! I'm a big fan of the stealth and utility you maintain with this down-firing box. I have a very similar setup (pics at https://www.explorerst.org/threads/custom-enclosure-pics.6164/post-78840), but running a JL 12TW3 in mine. @UNBROKEN s comments on dual sub frequency cancellation are...

    Wider tires?

    It doesn't show the size, but I can assure you the pics in this earlier post are Pilot Sport A/S 4 295/40ZR21 on stock wheels. Still going strong. https://www.explorerst.org/threads/wider-tires.4878/post-78822

    Rattle noise in front end?

    It may not be the strut itself, but rather the strut top mount. Seems this is a common failure point on these Explorers. I think I had the same problem as you... it sounded like a dull knock when crawling at low speed in a parking lot, but no issues with ride quality. Fortunately for me, the...

    Audio System Overhaul

    The harness with the CAN wires is the large 20-pin one that is mostly speaker wires. I'd left it disconnected at first, and the screen would power up but the audio would not turn on. I had to shave a key on my factory harness end to get it to fit into the socket on Zen. Maybe your installer...

    Timberline Skid plate

    Just found an email saying the part I ordered from Levittown on 12/13/2023 has shipped. I thought for sure that order died long ago. I guess they finally started stamping these things out at the factory.

    Wider tires?

    I've removed them, pretty shortly after install. The road film was obnoxious after a rain. Also, it may have been a coincidence, but my struts started knocking right after the new tires and spacers were installed. I loved the look, but still a bit leary of wrecking the new struts Ford bought me...

    FP Tune or ZFG?

    How about DMS so you have both? I have normal mode running performance and sport running race. I'm not sure what ZFG does with the tranny settings in the drive modes. Normal is very daily friendly even with the performance tune. Feels stock until you step on it. Sport does seem to behave a bit...

    Pirelli tires

    The foam detached on one of my stock Pirelli's near replacement time. Of course this happened on a road trip, so I was driving highway speeds with a very unbalanced tire. I was already considering switching, and that sealed it for me. The Michelin Pilot Sport A/S 4's I replaced them with do...

    Front end clunk/rattle

    Seems to be more than a bad run given this is an issue on 2020 - 2023 models...

    ZFG question

    I believe like me, people are hesitant to assign the performance tune to normal, and this is largely based on how the stock sport mode changes the throttle sensitivity. When I got my DMS tune, I reasoned that I wouldn't be buying a tune if I didn't want extra performance, so I took the leap and...

    ZFG question

    You get to pick Stock+, daily driver, or performance on most modes. Race is available on normal and sport. Tow only allows tow. At least that is what the current request form on their site allows. I'm pretty sure I picked stock+ for eco, and it feels very similar to pre tune. Since I don't...

    ZFG question

    ZFG question

    DMS has launch baked in, no additional cost. I've only used it once myself, not sure how using it will affect reliability. I run performance in normal drive mode with race assigned to sport. There is a notable difference with shifting in sport, with the shifts being a lot more firm. I'd imagine...

    Customer Satisfaction Program 22N17 - Easy, and inexpensive, DIY.

    Saving this thread... I'll be ordering the parts soon. Thanks for sharing.

    Intercooler

    FWIW, I never noticed turbo lag before installing the IC. Maybe it was there, I just never felt it. It is definitely noticeable now. Still very strong off the line, but puts you deeper in the seat once it gets fully spooled up.

    Having fun without losing towing capability

    Technically yes, but the FP warranty requires installation by a certified mechanic. If they see a recent key cycle reset while investigating problems, I'd expect some challenge. From Ford's perspective, they can't tell what tune you were running prior to that reset. You may want to look into...
