With our 1LT A6, at only 278ft lb tq, seems like it's kind of low for the weight of the car.
As noted on the SS---426hp/420 ftlb TQ, almost a 1:1 hp/tq ratio---it can effortlessly accelerate and doesnt need to be revved to 4000 rpm to feel alive getting normal driving or a little agressive, I'm sure.
However, for our V6, we only get 278, and wish it was more like 317-320 ft lb TQ, for a similar HP/TQ ratio of 1:1, like an SS.
So why only 278? Is because it was programmed from GM this way, shift points, etc., or the gearing is not as good?
In meantime, I've def learned so far that it's ok to be more agressive on throttle on this car---seems like it likes to revved as you said, and gets bored and sluggish w/ lower rpm, LOL.

Because engines are still very much mechanical beings. It goes much deeper than computer work. Valve sizes, camshaft profiles, piston sizes, crank stroke, head flow, intakes, etc...the engine doesn't make high torque because that's not how small naturally aspirated V6s work. Its extremely common for a motor of the size to make more HP than TQ the way this one does. It's simply the nature of the beast.
The Ford Ecoboost 3.5L V6 makes 367HP at 5400 RPM and 420TQ at....2500 RPM. Because, among other things, they stuck twin blow dryers on it. That's the exception.
Yes, the 6.2L doesn't need to rev to 4000 to move because it makes far more power down low. You have to understand how an internal combustion engine works before you can compare to wildly different engines such as the LS3/L99 6.2L and the LFX 3.6L. They simply will NEVER act the same. They having nothing in common aside from running on gasoline. They make way different amounts of power in different places. No computer tune, CAI, exhaust, or rear end gears will make one act like the other. Short of $6K investment into forced induction a V6 is going to act like a V6.
278TQ isn't much for a 3700lb car, but if one drives that engine like GM designed it to be driven, it motivates these fat Camaros just fine
Stock for stock, it will never compare to a V8 but I wasn't spending $7500 more to get to a entry level 1SS and then paying even more on insurance than my already high truck premiums.
