I pulled my injectors today and brought them to a local shop. He has one of those gizmos like in the picture that MDG posted. 1 day turnaround. Removal is simple like others stated. I'll let you know how it turns out. Boat was running good, but what the hell, it's raining here today and it gave me something to do.

Yes. Frank was the guy there. Nice guy.
Injectors are back in. The only thing that I could say to watch out for is... When reinstalling the injectors, put the fuel rail side in first then when all are in place push it into the motor side. Be careful not to pinch the "O" ring on the rail side when installing. HOW DO I KNOW THIS YOU SAY, Let's just say I found out the hard way. After doing the full reinstall Plenum, wires and hoses, then checking for leaks by turning the battery on and turning the key to the prime position, gas LEAK, Oh crap. Removed Plenum, and rail and then pulled the leaker, I noticed I pinched the "O" ring. Flipped the ring and reintalled injector. Checked for leaks before reinstalling plenum. All is good now. Ready to go boating.

Sorry For the crapppy chart, but my scanner is not working, So I'm just typing in the results.
Injectors now flow to within +/- 1% and are at or above OEM spec.
3 of the 8 injectors failed the Leak Test at 80psi.
The spray patterns were good from the start but the pulse was slightly off.
SouthBay Fuel Injector service did the cleaning. They said that this type of high flow injector does not have a tendency to clog. But seeing how they were already out of the motor and I was there with them in hand, I had them do the work anyway.
