I have the slight throttle response delay as well. One thing I've noticed is that when the throttle is pushed down, the oil pressure drops immediatly (roughly 5 psi) and then the car will accelerate. I would possibly suggest it may very well be the time delay in the VVEL opening up to accelerate the car. With heat soak and high oil temps, it could very well be the changes in VVEL position causing the delays.
