If you can get rid of them I would. They are not made for our engines.
Check this out and call Jon at FIC.

The only place you will find the right injector data for these is in the DVD from Greg Banish. $250 from Summit.
I personally ran these and they are ok but do not tune very good. The injectors spray the front and rear of the intake ports and the fuel puddles on the valve which causes inconsistent fueling.

The big trick to using different spray pattern injector is to recognize that the fuel to wall impact factor will likely need some significant work. I would start by increasing this table by ~20% and work from there.
Hey Greg,
Would it be possible if you could elaborate on this? If its going to be a royal PITA to dial in these injectors, id much rather buy a new set of injectors..

I want to use these injector on my boosted 98 4.3L V6 Jimmy.
All there is under injector control is, offset, offset multiplier, flow rate, flow rate modifier vs. volts, short pulse limit, min pw and short pulse adder. Then under Injection Timing I have , Boundary and normal.
I'm looking at this, (http://www.fordracingparts.com/parts/ics/m-9593-m39.pdf) right now and want to enter in the necessary info into my tune.
My question is, since I have to scale these injectors to my fuel pressure does that mean that other things like offset, offset multiplier and all the other stuff need to be scaled to? Or does all that stay the same no matter what the FP is? I don't have flow rate mod vs. Kpa and my FPR is vacuum controlled.
