Ford Performance Tune for 2018+ GT

[Rpinaiii]

I recently replaced the factory grille with an aftermarket mach 1 type (fully open mesh) and a Velossa big mouth on the driver's side. IAT is now 3-4 degrees above ambient when moving even at low speeds. I used some reflective DEI tape on the FP airbox and even in 90 degree temps the IAT at idle was right around where the stock air box was.

Overall I'm glad I did the Tune / intake / TB. Can't decide now whether I want to do 4.09 gears first or the digital dash conversion. Good trouble to have I guess.

Well, both the 4.09 gears and the digital dash conversion are going to cost you about the same amount of money. Unless you can install the 4.09 gear yourself or pull out the differential and then take to a shop can save you money too. But, you will get more fun out of the 4.09 gears lol. I also want to do the digital dash in the future.

I used to do gears - not anymore - it annoys me to no end. A local Mustang shop will do it if I bring them the pumpkin, with Ford Performance gears and master install kit for $250. So roughly $680 or so all in. Pulling / installing the rear pumpkin in a S550 is really straightforward, I've done several.

I can order all new Ford digital dash parts (no telling when I'd actually get them - but that's beside the point) including $300 core charge for the instrument cluster for a tick under $1400. I have FORSCAN and I would install myself.

Just finished installing and uploading the tune, and my car is throwing a PO61D Control Module Engine Air Mass Performance code. Anyone see this happen and how to fix?

Check all you work sounds like a bad connection

I cleared it, started the car and let it run and it never came up again. I will check again tomorrow and go for a drive.

Alright so after my brief trouble there, I love what this tune has done has done to my 10 speed. So much smoother and quick to accelerate, as everyone says, the butt dyno approves. I loved my car before and this tune makes me love it even more. If you are on the fence, make the plunge and grab it at Levittownfordparts.com for the best price. You won't regret it.

Glad you got it resolved. Lots of us like this kit also.

Just installed the kit this week and as everybody else, I can just recommend this upgrade ! The driveability and especially the behavior of the AT10 is a must ! No more random stupid mess when running low in 1st gear, it'sfast and smooth from 1 to 10 !

But, I wonder if you guys have trouble with the lateral foam piece. I couldn't install it better than that :

Tried multiply times, but I feel like it's gonna tear off if I pull more upwards.
I saw some pics where it's properly "closed" and some like mine ...
Any thoughts ?

Cheers,
Yves.

Don't forget to do a KAM reset. Wakes the baby up in a Huge way.

I believe the majority of us weren't able to get it right. I even unscrewed the entire top piece to realigne it with only a slight improvement. I just said f*** it and stuffed a piece of insulation foam in there to cover the gap.

I'm a little bit more confident that I didn't do anything wrong
Adding some pre-taped insulation foam was my next move...

I completely separated the intake tube from the airbox when I installed and it helped a lot for this issue and to avoid rubbing on the hood blanket as well...

The hard foam backing needs to be on the outside of the airbox.

Thanks !
I tried again this afternoon but like others the top part of the airbox is popping up and is completely in its correct position when the hood is closed only. So when I kept pressing on it I can put the foam correctly and it’s ok. As soon as I release the pressure it goes away.

I’ve put some auto adhesive rubber and it’s all good for now…it feels like a poor design though.

BTW is it my mind or what ?! I feel it’s louder/deeper through the exhaust ??

I agree. It's poor design. I am actually going to order a GT500 airbox and try it. Looks like a much better fit even though the GT500 also uses that stupid foam pad.

Yes. Your observation is correct. The car is louder and deeper after installing this kit.
