I need a more detailed description of your problem. Particularly, why you replaced the compressor, whether you replaced the receiver/drier and what you used to flush.
The pressures you listed are within range (but the high end of the range) if it was a hot day. If it was a cool day, those pressures are too high. I generally do all readings at 1500 rpms, so it would be more helpful to me if you would post pressures at that speed, and also the outside/ambient temperature (in degrees F). It is important to get an accurate reading on ambient temperature. Use a rock to hold the accelerator pedal down while checking the pressures. Give the system a minute or two to stabilize before reading the pressures.
The Seiko compressor has a notorious problem for the clutch gap to get too wide. This usually manifests itself when idling in traffic. BillJ has an excellent write-up on this on his site. However, it sounds like you are doing ok while idling, but not ok while driving. Which indicates that you are not having the clutch gap problem.
Problems while driving can be caused by the evaporator freezing. Does your anti-frost switch work? The anti-frost switch on one of my cars is broken and I have a similar sort of problem. You could also have something weird going on with the expansion valve.
The condensor is not your problem, and there is no reason to remove it to clean it. In fact, if it's dirty, you are better off cleaning it yourself by removing the grill and using a small screwdriver to pick out the rocks and bugs, and straighten the vanes. The high side pressure will drop dramatically on just about every car if you spray the condensor with a garden hose. I don't think it's much of a test for anything.
