That said I've never noticed any lack of performance from that. But I only leave the plugs in for a year. Also gets on the O2 sensors, cats, and supposedly fuel injectors but I haven't pulled the injectors to look
100 octane would gain power on a gen 4 Coyote as it would still add timing past what it would get on 93. E30 is what, 96-98 octane depending on who you ask? It gains power as well.
Now, is it worth the high price of whatever 100 octane is in your area (it's double the price of 93 here), for a...
Do you really want "dirty" oil circulating through the engine even though some lab test says it's okay?
It'd be like taking a bath after four other people. The test strip says it's good for a few more uses!
Some people call E tunes 'email tunes' as opposed to dyno tunes. So I wasn't sure if that's what he was talking about and then wondered what an O tune would be...
They won't magically find more power in a year. You will never get the gains out of an NA car (especially one tuned to the edge from the factory like the S650) that you will see from a tune on a factory turbo car.
Honestly, not much.
Headers are $$$
Tune is $$ and will get you like 15hp on 93. Would be a decent gain on e85 though.
Lighter wheels (say 20lbs each wheel) and carbon fiber/aluminum driveshaft are $$
Nothing really to be had with the airbox or throttle bodies
You could have the intake...
What is O tune vs E tune?
They only said 20hp on YouTube (and most other tuners were saying somewhere around 15-20hp on 93 was all there was to be had)
Here's what would satisfy a lot of people, but Shelby will not do:
1. Give a couple cars to some YouTubers and whatever magazines are left.
2. Get some performance data. This way they can legitimately say things like "5 seconds faster around ______ raceway than a Standard Dark Horse or 2020...
Yes
Slightly quieter/cleaner sounding with cats than without. But still much louder than stock.
The risk is still high depending on how much power you are making and what kind of cats you get. Cheaper cats and lots of power isn't a good combination.
