MY 930 Torque/Horsepower Curve

Porsche 930/911 Turbos up to 1989 are well behaved and can be forocious (At least the ones I have driven). My question is: My particular 911 turbo (1987) seems to have a torque curve that comes on hard around 3200 and begins to diminish above 4200 RPMs. It pulls very strong. Example; Going from second to third getting on the freeway I leave 2nd gear at 4200 and hit 3rd and the RPMs will be about 3000 and then you have to wait a second for the boost to come back on...Is this normal? My car would be awesome if you went from gear to gear on boost.. I would think that .8 bars of boost would generate a longer torque curve into the 5K RPM range ( above the 4200 RPM peak ) remedying this phenomenon. Does anyone else experience this 4200 RPM peak torque. Can it be cured?
