Depends on the car. The EcoBoost Mustang doesn't like having much more than 100-150hp added to it on the stock engine. That's not much (percentage wise, 30-50%) compared to what you can add to say, a Coyote.
You really don't need to change anything. Sure, for traction you'll probably want to...
It holds almost all of that to 8,000 rpm though.
It's all about average HP anyway. I'm sure they could have found a peakier cam profile.
Their S550 car had comp cams stage 3 bumps ticks in it, 570-something on the dyno, with a cobrajet.
The Cobrajet is going to give you more usable RPM, not necessarily make more power at the stock RPM ranges. It may not make more power on stock cams (or if it does, just a tiny bit more near redline)
Do you have dyno charts of your car with both intakes?
2018 intake vs cobrajet but the idea is...
Actually, Nittos aren't even that cheap anymore.
Let's look at TireRack.com, 285/35ZR19
$267 - Hankook Ventus V12 is the cheapest (but it's on closeout)
$281 - Sumitomo HTR
$286 - General GMAX
$298 - Kumho Ecsta Sport S
$303 - Yokohama Advan Sport (closeout price)
$319 - Firestone Indy 500...
fun fact, those tpi/lt1 throttle bodies were only 2x48mm
