[Peppy]

I have used Steeda for my 2021 GT I can swear by them, they are amazing to work with and was very nice in helping with any questions ive had!

[chevy]

One of the best things I did with a 93 tune was a bulletproof rear end with 3:73 an aluminum driveshaft differential cover and all the parts was FordRacing with the Steeda under drive pulleys on a 2003 GT and it was a over night difference!

[strassafrass]

It's wild to think that most of these things were freely available in the past with the turn of a screwdriver on a carburetor. How far we've come.

[marcasswellbmd]

God I love my 17 that has none of the digital crap on the dash.. I am old school and love my Real gages, It's nice to have oil pressure and vacuum pres, on the dash instead of the extra vents.. ..

[alvinxsingh]

I wish you guys would do Camaros too. I love the way you guys look at performance. I know lots of Camaro guys go to the track too and would love some Steeda track performance upgrades. You guys should!

[chopdogrulz]

Didn’t know you guys did tunes. I’ll definitely look into that for my ‘18 PP1 GT. Also, did you say you have tunes for Ford Fusion? 🧐

[bkeywsg]

Great video Scott. I have a 19 GT with the 10r80. Does the Steeda tune improve the shifting of the trans as well. Also is your e85 tune a flex tune or do you have to run the tank down completely before flashing the e85 tune

[jd-pynm]

had a tune and CAI on a ford fusion back in 2007 I think its time again and maybe on a mustang this time!

[PedroSoliz-iywc]

Question, I have a 23 Mach1 fully loaded tr80 track and performance I want to get more HP but don’t want to purchase items that aren’t upgrades to what I already have from factory my main concern is the air intake, I do want a tune and long tube headers and H pipe but is the intake going to be an upgrade the mach1 already comes with the GT 350 intake

[MyPeopleNeedMe]

As of 2025 are you able to get a custom tune for the 2024 mustang GT? When I'm on the custom tune page there's no option for the 2024 year.

[fgj]

Are Steeda custom tunes new? I've never heard of them before. Are they custom tunes like Shoemaker, PBD, Lund?

[JuanFernandez-zmiy]

I have a roush supercharger can I used one of your tuner.

[tywil]

Where can i get Steeda lettering for my rear 2020 GT deck lid?? I've searched to the ends of the earth and I've seen one car with them near me..

[Speedfreak_ZXR]

The car sucks in cooler air with the hood up and will elevate dyno numbers for the intake while simultaneously lower IAT’s. Close the hood and run the dyno again to see the proof in the pudding.

[MaverickOTW]

Can you use a conservative custom tune with the Ford PP3?

[gordydexter]

Great video Scott, so awesome to see the gains made!!! Very impressive!!! I heard from some friends that we are very close to breaking the encryption on the S650 ECM/ECU. That will be great news when it occurs!!!
Is there any concerns about using E85 fuel???? I live in Maryland and E85 is everywhere. I don’t want to damage my cats, exhaust, etc.
Your thoughts please????
Cheers‼️👍👊💪🇺🇸😎🔥🐎

[S.A.S.H.]

I wonder how much can I gain with a custom tune on my 2020 Ecoboost HPP. Has active exhaust Magnaride and JTL CAI.

[davidperez]

Will do tune once my extended warranty is over for sure. My dealer dont like tunning. :(

[MisterJ.J.]

Will the steeda custom tune also work with the addition of long tube headers with catalytic converters without setting off the check engine light yet still make a lot more power?

[ClayMurphy]

Is this a E85 flex tune or a dedicated E85 tune? If it's a dedicated tune, what does the E% need to be no less than? As you know, pump E can be anywhere from E50-E85.
