    Any tips when changing out the electric intercooler pump?

    Noticed my IAT2 readings being waaaay too high the last one or two times I drove the car (190 to 200 degrees constantly). Today I decided to check into it. I jumped the ICP relay and I have 11.9 volts at the harness that plugs into the pump...but I don't hear/feel the pump doing anything. So...

    Finally made some headway on my Knock issue

    I've been chasing +knock readings for a while (see my earlier posts in this thread). I found/fixed a couple of small things over the past that I thought may have contributed to false knock, but nothing solved it. I of course tried different fuels, torco, etc.. Knock was still present. I...

    Lower control arms loosen after launch?

    I have the non-adjustable BMR lower control arm (TCA019) with relocation bracket (CAB005). I'll torque the three bolts down and all is great for a while. It feels amazing, it rides wonderfully (dare I say better than stock), feels tight & well planted, etc.. However, after the very first...

    Help diagnosing my rough running 2013 GT500

    (Sorry in advance for the long post) Here's what it's doing: Marginally rough idle (not terribly bad, but noticeable). Surging when running normal highway speeds. Seems most noticeable in the 1800 to 2600 RPM range. Extreme popping on deceleration. I mean like 4th of July fireworks going off...

    2013 GT500 door speaker brackets for aftermarket speakers?

    I was going to upgrade the speakers on the door of my car today, but it doesn't look like what I was expecting: So there's no way to simply bolt in these new 5x7's that I have. A google search yields info on using 11/12 Ford door speaker brackets. Model#'s: 4R3Z-18B947-AA and...

    Question for those runnin 11" rear wheels:

    I recently purchased a set of Forgestar CF5's (20x9 +35 and 20x11 +55). Two main questions: 1. I jacked the car up, put the rear rim on and it rubs against that small angled part that some people remove to run wider wheels. Sorry I don't know the technical name of the part. I've read that...

    Any idea why I frequently have to reset the ECU? (poor performance)

    Seems that over time (about 1 to 2 months) my car becomes noticeably sluggish with a very rough idle and lots of popping on deceleration. When this becomes noticeable I pull the negative connection to the battery, turn on the headlights, and open the doors. Leave it like this for 10 minutes or...

    Data log points to monitor, good/bad values, etc..

    I've been monitoring my cars data more closely here lately. To be perfectly honest, I'm not sure what a lot of the data I'm recording means in simple relation to good vs. bad. I've researched the actual data points I'm monitoring (will list below) and learned some about what they do...

    Aftermarket axle recommendations?

    Well, it looks like I have another bent axle. I've noticed some of the familiar squeaking appearing again. Checked it the lazy-man's way this time...stuck a go-pro on the side of the car pointed at each tire and sure enough, wobble city on the driver rear. This makes the third time replacing...

    Rough paint where spoiler meets trunk lid

    I noticed some stains running down each side of the S H E L B Y lettering on the trunk of my 2013 GT500. They appear to emit from a rough area at each corner where the spoiler attaches to the trunk. Attached a photo of each corner of the trunk lid / spoiler base for reference (I had already...

    Having h-pipe installed but tune hasn't arrived yet.

    I'm scheduled to have an off road H-pipe installed first thing in the morning however the tune for this mod hasn't arrived yet. Would it be safe to drive 20 miles or less (home from shop) without a specific tune for the off road h-pipe or should I postpone the h-pipe install until I have...
