GT350 Engine Mods?

[trackjunkie]

Was the rumor of Ford producing some type of "trackkey" style tune for the GT350 just a rumor? There are a few features I wish they would ditch like the way it holds the RPM for a second after you lift off. The trackkey option for the Boss was awesome, I wish they would do that for the 350.

I would love to get rid of the rpm hold, it's really annoying to me. Sad to hear they canned it. Is this something a typical aftermarket tune could get rid of?

How much do you pay for 100 octane?
Its around 8 bucks a gallon here, and significantly more at the track.
I usually pay 2.50/gal or so for e85 and with the savings in fuel cost I can buy a warehouse full of fuel jugs to bring to the track.
I have a 55 gal drum, a 25 gal drum and 8 fuel jugs. When the price gets closer to 2.00/gal I go fill up.
Then I just pump from my own personal gas station here in my shop as needed.
The real bonus is that it runs way cooler than any gasoline-racing or not-so you can tune much more aggressively.
On my blower car it's a difference of more than 100 hp so it's a no brainer for me.
N/A cars will benefit from the cooling nature of e85 too, although not nearly as much, however the costs savings do still add up.

I know this is an old post, but hopefully you will see this. I have a 2019 GT 350 stock. I track the car and will be at Kansas Speedway this weekend. The local VP guy says I can run HP 101 or MS 109. Do you know either of these fuels? At this point I do not want to tune it to void the warranty. So how do these fuels work with a factory tune? Thanks for any help.

Yes, you can run them.
MS 101 is plenty for a stock motor/tune. Probably wont be any faster, but it will give you a safety margin against detonation. Do you NEED it? Probably not.
