I do know that in general, 4v engines tend to make their torque at a higher RPM than their 2V brethren...
Here is a picture of a Torque/power curve I found comparing Gen 3 and Gen 4, but I find the initial torque curve the most interesting (off of LMR website https://lmr.com/products/2022-mustang-gt-vs-2024-mustang-gt-dyno) Now, I don't know where they started pressing down the accelerator pedal...
