Yeah I see what you're saying and a lot of that is what chad said in the super conservative stock tunes. That's def why in almost all stockers there is a big demand for custom tunes cause they just don't give you the timing/fuel tables that the performance guys want from factory. A lot may have to do with durability concerns because the more agressive a tune normally the less life you'll see from of the entire rotating assymbly but thats not ALWAYS the case.
On top of that its all engine engineering/design so if we can't get to 500+hp with a tune on this new 392 then id say someone has some questions to answer.
BUT FTR, so everyone knows, the WK SRT8 6.1L motor made around the claimed 425hp at the crank which makes out to almost 70/hp per litre exactly which on a N/A platform is impressive, all your F/I setups will make 1.5-2x more power but that's what you pay for.
THE NEW 6.4L 392 makes a claimed 470hp which is about 74 hp/litre so right there we picked up 4hp/litre on top of what it would have been on the d motor design if we just increased the displacement so clearly they've improved something else. Head design, intake/exhaust design probably being the main factors but Im happy with what they've done and hopefully well have tons of aftermarket options for this 392 but I wont hold my breath haha
Like I said earlier, for all the complainers/haters/naysayers, you don't have to buy this jeep just cause you had one and if you didn't you certainly don't have a gun to your head. Why not just go get a yuppy boy x5/6 m and call it a day. The Jeep is a working mans suv, the bummer is just the insecure midlife crisis yuppy mans car lol, but this is an argument that can't be won by either side so feel free to flame on
