Looks like it is bogging down in too high of a gear. Related to the AT kickdown cable dis-calibration you went thru last year?
What are the engine RPMs when you have pedal to the floor while climbing the hill? Pedal to the floor should immediately drop down one or (often) two gears and get you in the 2500 - 4000 RPM range, where the turbo is able to help the engine make some real power. Lots of noise & excitement!
Pretty gutless below 2000 RPM.
