  1. Sync3 nav updates - for free anywhere?

    It's been a few years since I last updated the maps in my Sync3. This was apparent to me when nav failed on me last week when I wound up getting lost b/c Sync3 pointed me to a road that no longer exists. I remember being able download (for free) the map updates. Darned if I can find it now...
  2. GT350/Airaid 863-399 filter on the Steeda CAI (model 555-3228)?

    I have the GT350 airbox/CAI and have used the Airaid xxx-399 filters with it since the beginning. https://www.airaid.com/863-399-replacement-dry-air-filter?srsltid=AfmBOorXWXuq_h1eMoKhPPSZTs41-Eboy72X3kXRMDCVpilRxvLJzvVZ The GT350 Airbox comes with a foam side piece that helps seal it against...
  3. Map light problem

    I have a weird problem with the map lights in my 17 GT. When either door is opened, the map lights come on like they are supposed to. But with the doors closed, pressing the button on the map lights does nothing. This happens with the headlights on or off, so don't think related to...
  4. Caliper swap - bleed before and after or just after?

    I'm in the process of swapping my 4-piston stock calipers for the 6-piston Brembos. The brake fluid in the system is 82K miles/8 years old. Yeah, I know. Neglect. I am planning to flush the entire system after the new calipers are installed. But, being that the lines are currently full of...
  5. Strange noise coming from rear end of car

    This is driving me nuts and I hope you guys can help. 2017 GT, 83K miles, no pumpkin or rear axle mods. No accidents. Car has not been hit. My car has developed a noise coming from the rear end that increases with road speed. It sounds like "whup-whup-whup-whup." Almost like what a tire...
  6. Math Help: Calculating displacement of a tube port

    I'm horrible at math, so I use online calculators whenever possible. I'm trying to determine the external volume of a cylinder, or, the displacement of a tube port I'll be using for my new sub box. I used this calculator; the numbers I plugged in are accurate...
  7. Have a custom sub box? How is it anchored down? Post pics.

    After a few years of having a JL Audio Stealthbox bolted down in the factory location in the trunk, I'm getting ready to build a custom sub box that will mount behind the back seats. i'm planning on using the center bolt for the rear seats to anchor the box down, but I really have no idea how...
  8. Tuning Related: How to connect REW/get pink noise from laptop into HU?

    Rather than post this question in my build thread, I figured I'd post it here to make it easier for people to find. I'm ready to start tuning my system/DSP using Room EQ Wizard (aka REW). REW has a built in pink noise/signal generator and using it would greatly simplify the tuning process. I...
  9. At what volume setting does the 400A head unit distort?

    I know this is a longshot, but possibly someone might know. I'm trying to determine the maximum clean output setting (before distortion) of the 400A head unit (I have the 9-speaker shaker system.) I have a SMD DD-1 distortion detector, and tried to use it, but it didn't show any input...
  10. Mustang System 2.0

    This is a "Work In Progress Thread" vs. a "It's all done and here's my build thread" thread. It will keep me motivated to keep going! Back in 2017 I said I was happy enough with the stock 9-speaker Shaker + Stealthbox install. It was good enough, and I wasn't going to deal with the misery of...
  11. Anyone remove the rear speakers to let the subwoofer output in?

    Getting ready to start my new system install and since I'm going to have the interior halfway apart anyway, I'm toying with the idea of removing the rear speakers to let the bass from the sub into the cabin. I'll be disconnecting the rears anyway; was just going to leave them there, unplugged...
  12. GR3E-9F991-AA throttle body - what sorcery is this?

    Now that I've done the '18 mani/stock TB swap on my GT, I'm left with the GT350 TB that came with the FP PP2 kit and the spacer. My TB is clearly marked part# GR3E-9F991-AA. A Google search turns up exactly two hits, one on Ebay. A search on Tascaparts turns up NOTHING. What the heck do I...
  13. Using two different tuning devices?

    No concise way to say this in the subject line. I uploaded a Lund tune today with my new SCT X4. I don't see an option anywhere in there to change my tire revolutions per minute to fix my speedo. I didn't check against GPS, but I'm pretty sure it's off..reading high compared to how fast I...
  14. Looks like I need a new intake manifold--upgrade time?

    My PP2-equipped GT has developed the #8 cylinder misifre/random misfire problem, which is typically indicative of the butterflies in the IM being busted. Swapped coil packs and the problem did not move from the #8 cylinder. I haven't pulled the #8 injector or plug, but based on everything I've...
  15. Torque spec for front brake line to caliper - verify it's 35 ft/lbs?

    I didn't see this spec posted in the big "specs thread" at the top of this forum. I'll be replacing my front calipers along with the hoses all around (going to steel braided lines). I saw in this thread that the brake hose to caliper torque specs for the rear are 35 ft/lbs...
  16. Was I sent the wrong radiator? (PP vs. stock 5.0 rad)

    I think someone's trying to rip me off. I purchased what is supposed to be a new PP radiator for a 5.0 engine. The box I received had been opened and taped closed. The part number on the radiator itself does not match the part number on the box. The part number on the box is correct, but the...
  17. Changing from semi-synth to full-synth--anything to look out for?

    After my car nearly fell off the 4-post lift and got greasy-handprints all over it too, I've decided the dealer will no longer perform regular maintenance on my ride. I bought a service plan for it, so that's why they were doing it. For my first DIY oil change on this car (not my first EVER...
  18. What size tubing fits on the radiator petcock?

    From the "I always wondered about that" files - What size tubing fits on the radiator petcock so that you can drain the radiator neatly into a bucket without it splashing all over the place? Thanks. Also, related: Where do you take your old anti-freeze? Two auto parts places near me take old...
  19. Steeda driveshaft safety loop instructions?

    Anyone have the instructions for the Steeda driveshaft safety loop? Steeda used to have the installation instructions for all their products right there on the product page but no longer do. Changing that was a mistake IMO. I'd like to see what's involved in the install vs. the BMR (who has the...
  20. 1500HP half shafts + 850HP driveshaft - make any sense?

    I'm planning to go FI of some type (undecided ATM) in my DD in the next 6 months or so. Looking at doing "mods that matter" first, to avoid problems later. Looking at upgrading the half shafts and the driveshaft. What I'm finding is that many aftermarket driveshafts are rated at 850HP, while...
