Ford Performance Tune for 2018+ GT

What's the secret to removing the 10mm nut holding the sound tube to the firewall?

I don't want to just rip the tube from the firewall, and I've spent many hours today trying to remove the nut.

My install of this kit is on hold because of this issue.

The instructions have you remove the driver’s side wheel and wheel well panel to access the nut.

I just pulled mine off instead of doing that.

I tried that but the opening was so small that I couldn't get it that way either.

Bust your hand open trying, rip it out, or leave half of it on and cap it. I did the latter.

A couple extensions and a swivel allowed me to reach it. No taking the wheel off or ripping it off for me.

I used a 1/4 drive 10 mm deep socket and small ratchet. Could only get about 1/8 of a turn on it at a time, but got it off without to much trouble, just took a little while.

I used a ratcheting wrench and patience. It was off clean in a few minutes.

Just rip that sound tube off the nut. Lol thats what i did. I took off sound tube like after a month of ownership though, not for the kit. The cheap plastic breaks away easily from firewall. But understood if people dont want to do that.

I removed mine without breaking the plastic, I just gave gentle but firm tugs UP away from the engine bay. The tube isn't captured on the stud, just smooshed down by the nut.

I really don't understand the supposed official procedure though. That "window" through the wheel well not only is too small to be useful, but there is a bunch of stuff going through it too.

Ok, so I wrote to, and received a quick response from FP about this kit for AUS vehicles. Unfortunately it’s not an option.
It’s a shame as while the tune is “conservative” and that’s ok, I’d really the OEM A10 tune update over any of the aftermarket ones.

Thanks to FP for their fast response.

Good Morning-

The calibration is different for US/CAN and EU/Asia Pacific (which includes Australia). We do not have a calibration for an Australian market car, and if you were to purchase this kit and try to download/install it, it would not work simply because there is no calibration available.

Hope this helps clarify things.

Hi Team FP,

I am looking to purchase and fit the M-9603-M8B, 2018-2020 Mustang Performance Pack on a FN Mustang GT (2019) PP1 (ish) AUS vehicle.

The FP webpage for the M-9603-M8B states:

“Calibrations are for US and Canadian vehicles only “

Are you able to elaborate on this further please? I did see some discussion on M6G this may be due to additional Catalytic Converter hardware i.e. GPF, like on the Euro' spec cars, but we do not have that system on AUS cars.

Is the US/CAN tune actually different from the AUs tune, or is this statement just about/based the receipt (or not) of particular country legislative approvals for the new tune?

Should it be the latter, and I purchased the pack, would FP still allow me to download the new tune and upload it to my AUS VIN vehicle?

Expert definitive advice regarding this kit for AUS vehicles would be greatly appreciated.

Thanks.

Maybe Mustang Motorsports in Australia might be able to get a licensed version for Australia?

They are in MEL and also sell FP parts.

Thanks but no. It would probably be twice as expensive or more through an AUS retailer.

Ask or search in the UK forum man. Unless my memory has gone totally bad and I dreamt the whole thing, I'm certain there was somebody here in Europe mentioning getting this tune from Ford in an European version. One thing I am not sure about is whether it was the 2015-2017 or the 2018+ version.

Yep, FP FM performance kits are available here in Oz, just not FN.

I finished the install last night. I decided to cut the clamp on the sound tube near the strut tower and plugged the opening.

This way, it would be easier to return to stock if needed.

I found it easiest to attach the intake tube to the throttlebody with the intake box resting on the apron, and then setting it into place one the tube was seated on the throttlebody and the clamp tightened.

Having a helper hold back the upper edge of the foam seal while you put the box into place also makes things easier.

Using the Pro Cal was an easy process with no issues encountered.

I haven't had a chance to drive it yet but I'll report back once I do.

@green97probe you might want to adjust your foam. The hard backing on the foam piece needs to be on the outside of the air box. From the pics it appears yours went inside under the upper air box part. I posted this a few pages back: https://www.mustang6g.com/forums/threads/ford-performance-tune-for-2018-gt.122943/post-3214193
It looks like your kit came with a much longer foam seal as well. Mine barely covers the hole at the bottom front edge towrd the headlight.
