How to accelerate in P&G mode?

Also, note that the surge is barely perceptible, you really have to be looking for it, at least in my vehicles. It is gentler than, for example, the torque converter locking in my truck (which itself is almost impossible to feel).

Could it be that the computer switches mode in WOT, and computes the optimal duty cycle for acceleration, whereas at 80% it does what you tell it and runs too rich without returning any benefits in improved acceleration? (by too rich I means spend too much gas for no extra return, not spitting out unburned gas)

I'll try to look for that surge on my Del Sol. 875RPM is darn close to idle, no suprise there...
