Need some help and input regarding engine (like a 760 loaded pulling a trailer scenario.

From stop to take off. Initial lag turbo builds boos to 5psi, trans shifts 1-2, turbo drops out of boost after shift, accelerates turbo spools as speed increases and very fast 3-4 shift. Pedal near floor to keep accelerating. Slow acceleration to lockup (smooth positive lockup). Foot to floor slow acceleration.

Using standard turbo with new core. .95 timing, new std nozzles pop tested.
Using Volvo 760 Zf with 4hp 24 front pump and a clutch set. Volvo valve body and gov.

Questions.

Does the Volvo 760 stay on boost continually when flat out?
Is the turbo sequence described above normal?
I never adjusted or disturbed the max speed screw, could I not be reaching max rpm as I had adjusted the throttle lever to throttle shaft after pump rebuild.
As I'm using the euro d2.4tic intake and intercooler I've no overboist control, Is that an issue?

The engine is stock, fitted to 04 discovery.

Tia.
