    275 45 ZR-17's? CEL or Failsafe Mode Problems?

    I'm going to 4.10 gears in my 5-speed GT and know I'll need more tire. I have the base "Torque Thrust" 17" rims. Has anyone tried running 275 45 ZR-17's on these rims? If so, any feedback or recommendations? Two local performance shops have recommended this size if staying with the stock...

    Failsafe Mode Deactivation?

    I love OBD! Like people in other threads, my car went into Failsafe Mode today for no apparent reason and actually shut the engine off entirely, in traffic. I'd been driving for about five minutes, everything was running fine, temp gauge was normal, nothing smelled hot. As the user's manual...

    17" Stock Rims, Wider Tires

    My GT has the stock (Bullitt style) 17" rims. I'm probably looking at 2XX 45 ZR-17's for extra grip when I go to 4.10 gears (manual tranny). What are the widest tires that will fit on these rims, front and rear? Also, can anyone recommend a tire that offers a good combination of grip and...

    4.10 Gears...Again!

    I know there are a bunch of posts out there, but I couldn't find this info. I'm specifically looking for input from 5-speed GT owners with 4.10's. 1) Rating of 1-10, 10 being highest, what do you rate the seat-of-the-pants gain going from 3.55's to 4.10's? 2) Rating of 1-10, how bad is...

    4.10's & Stock Pirellis - Traction Problems?

    Is anyone running 4.10's with the Pirelli 235 55 ZR-17's? If so, how's traction on the street when you launch? I'm considering going to 4.10's on my 2005 5-speed, but I'm concerned that I'll effectively run slower due to traction loss at launch. I went to 3.73's in my 2000 GT 5-speed, which...

    Speed @ Redline

    Anyone have a Motor Trend or other print that lists the 5-speed Mustang GT's MPH at redline in each gear? I have no idea what I did with my magazines.

    Cold Weather & 93 Tune

    Has anyone else thought that there car runs a bit rougher/underpowered in cold weather, with a 93 octane tune? By cold, I mean 40-50F. It seems this way to me. Only thing I can think of is that the knock sensors could pick something up and detune a bit, but that seems kind of extreme...

    Factory Shift Indicator Light

    Has anyone figured out how to activate the factory shift indicator light that's in the middle of the tach? You can see the outline with a flashlight, right below the 4K mark. It's shown lit up in some early dash pics, but apparently didn't get activated for production. I'm assuming it's a...

    Quick Review of Predator CANNED Tunes

    I purchased my Predator tuner from a local speed shop for $350. Been running it for two weeks. My only other mods are Flowmaster AT axle-backs, a K&N air filter in the stock airbox, and a Hurst short-throw shifter. Here's my thoughts, based on MY expectations when I bought it, which were...

    Yellow Driving Lights

    I've seen a couple of 2005+ GT's with yellow driving lights. Is there any point to yellow lights for visibility? Fog, anything? Or are they just cosmetic?

    Predator Tuner - Need Advice, Please

    I'm sure that this is covered in other posts, but I'm too stoopid to find one covering all these questions. I'm looking at getting a Predator tuner and custom dyno tune at a local shop for $600. I asked in the SE regional forum and everyone who replied told me to use this shop. I have a...

    Tampa Bay Tuner Shop?

    I'd like to get some minor tuning done to my 2005 GT manual, mainly to improve throttle response (hopefully just easy reflashing.) Any recommendations on a good tuner shop in the Tampa Bay area who knows the 2005+ cars? Thanks!

    Torque Management?

    I sometimes see comments about a custom tune getting rid of the new Mustang's "torque management" limitations. With the factory tune, does the computer control the engine to limit low RPM torque, or something? Even with traction control off? Is this in autos only, or also manuals...

    Updates on K&N Aircharger experiences?

    I've read a few responses on here where people are running K&N Aircharger kits with FACTORY tune and no other mods, other than some with axle-backs. Most of these were older posts, so I'm looking for updates. Anyone running K&N with factory tune have any problems, comments, good results...

    K&N - Stock filter replacement?

    Does K&N make a drop-in filter to replace the stock paper one? If so, know how much $$? I'm not expecting any power gains (or losses, I'd hope). But it'd be nice to not have to pay $15 every 10K miles or so to replace the paper deal. Also, I remember reading a while back that oil, or...

    GM Announces 30,000 Job Cuts, 9 Plant Closures

    Brutal. Even after cuts, for GM retirees, it's like Social Security bankruptcy looming for all of us, but sooner and two times over. http://www.mlive.com/newsflash/michigan/index.ssf?/base/news-29/113265114180420.***&storylist=newsmichigan...

    2nd Gear Downshift Missing/Backfire

    If I do a high-RPM downshift to 2nd (putting RPM's at 4K+) to get on it for fun/passing, I sometimes get serious stuttering and even a small backfire if I do it too quickly. If I blip the throttle to match revs (not easy with the new ETC system) or slip the clutch a little bit, this stops it...

    My Opinion - Flowmaster American Thunders

    I've had my Flowmaster axle-backs on my 2005 5-speed GT for a week now. This is my first and, most likely, only mod for the car. Bought them for $299 at a local performance supplier and had them installed by a muffler shop I've used before, for a flat $50 fee. Here's my thoughts: -...

    Flowmaster Axle-Backs

    I'm considering the axle-back Flowmasters with factory pipes. I've heard the video clips (which are so hard to judge) and they sound throatier and deeper to me, with a bit of "burble." I had 40 Deltas on my 2000 GT and F-150 and loved them. However, I've heard a couple of people say that...
