No power after engine swap; No power

I have a problem with my Geo metro vert that no one has been able to diagnose. I had a crate engine put in 2800 miles ago and since getting it back it has lost power over time. Started out not very bad weak, just thought it might get better during break-in, but the last time driving 40 mph was as fast as I could get out of it. 40 mph was in 4th gear downhill. If I went to 5th, it would immediately slow down quickly. Already had two shops look at it and stated they are clueless to what is causing it. Timing is on, new plugs, wires, rotatery button, and distributer cap. Replaced fuel filter.coil tested good. any help would be greatly appreciated.

No codes, catalytic converter fine, compression all at 150. Don't know of any specific tests were done.

Just throwing this out there...
First one to look for...Check the grounds at the back of the intake manifold under the throttle body first, clean and tighten...
Check charging system...
Check EGR valve and solenoids...
Test fuel pressure...
Last one to check but I have seen it affect driving, Brakes dragging?

Compression of 150 is low for a remanufactured engine. What was done to the engine when it was put in?

150 psi compression is below the recommended service limits per the FSM, 156psi is on the lower end of the service limits per theFSM. New " out of the box" compression should be around 200psi +/-. They will run with lower compression but usually with drivability issues. 150psi for a "new" re-manufactured engine is low!

Im aware that 150 is low for a new engine. But it is what it is. Still at 150 it should be able to pull itself. Driving one now with 90-70-70 that easily runs at highway speed.

Start with the things that geogonfa suggested. Fuel pressure especially.

Could you post a picture of the end of the distributor shaft with the rotor removed?
