6 speed cars with a tune running with stock hellcats?

Stupid throttle controllers don't do anything your foot wont.

🍿

Won't bother you if you have a 10R80

Hellcats can come with a 2.62, talk about low.

Here's how it goes: 1. Spend $1,595 to add Active Exhaust to your car when you buy/order it Not loud enough. Buy $300 H/X pipe because a $2,500-3,500 AE compatible catback is too much $$$ Then either: A) still not loud enough, spend $2,000 on active exhaust axle back or B) H/X pipe made it...

E30 mix no problem bone stock everything

I know JPC saw the same thing https://www.hotrod.com/features/2650-mustang-jpc-racing-part-1-modifications

The MT82-D4 needs 4.09 gears. Compared to the TR6060 in the Camaro, you're in each gear for longer. Part of that is the gear ratios and part of that is the Coyote engine revs about 1,000rpm farther. MPH ranges of each gear (2nd, 3rd, 4th): (3.55) MT82D4: 28, 39, 50 (3.73) TR6060: 30, 33, 38...

It wasn't 30%, but wasn't it a known fact that the DH didn't have the "feature" that the GT had where one of the TB's would slightly close at high RPM? I seem to remember it being a discovery when the cars first came out

Re-read the last sentence of that quote. And look at this graph to see what timing can do to engine hp

Cobra? Do they make one of those? I know they have the GT350 and the Supersnake.

Why is it not good for your engine?

Would have went taller in the back too. 27.0" at least

Why so small on the front? Should have went at least 275/35

It won't void anything that isn't drivetrain related

There's a few answers to that question. The ECU can guess based on AFR etc and add fuel accordingly (the 'old' way, called a flex tune), or the flex fuel logic can be enabled in the ECU. Or, you can run an e85 specific tune that basically just adds way more timing and fuel. In that case the ECU...

The stock tune is going to pull timing on 91 so you it's not like you can add timing and gain power with an aftermarket tune. 93 or ethanol (whether it's e30, e50, e85...) will allow more timing therefore more power.

They said it's definitely not.

What graph are you looking at? The aftermarket tune added power everywhere and extended the powerband another 500 RPM Where are you getting "narrower" from? It didn't lose power anywhere and the powerband didn't "shift"
