I purchased the engine brand new and installed it myself. Since the beginning, at full throttle RPMs do not go more than 2500. There are no alarms. It feels like the computer is cutting off the gas.

Yes it is.

Look closely at the TPS on the engine. It is on the throttle body. Make sure that it is not loose and moving when a helper moves the throttle handle.
