How to test fuel injectors? Crappy running at low rpm

A while back someone posted they pulled injectors and ran them to look at the spray pattern, check for deposits. I can't find that post and can not find the procedure in Bentley or Haynes.
Can anyone give details of pulling injectors and running them "full duty" to look at spray pattern. What leads to cross, etc.
My 88' Turbo is hesitating big time at low rpms and I'm running out of things to check...
New NGK plugs
New cap & rotor
Timing at 16 degrees
Dist. vac. advance holds vac.
No vac. leaks
Turbo bypass valve holds vac. and is fairly new
93 octane gas
compression 150-155 all cylinders
Car comes alive above 3 or 4 k rpm so I'm guessing fuel pressure ok?
Boost is fine
Any other ideas guys???
