Well, don't know what to say about your situation.
Maybe it's a problem with the programming that controls the engine and transmission! Perhaps it needs some Flash update to correct the behavior.
My 3.7L (with 4-speed auto) does okay if the system operates properly. If the engine is revving, I have power. My problem is when the computer fails to recognize I'M the driver, and I need power right now, yet it insists on keeping the torque converter locked in. Grr.
