Update: I am on the phone right now with a guy who has the GM 25170301 injectors, which SB said are the GM Black/Yellow. BUP posted the original part # 3857398 earlier, and mentioned they were black/yellow high pressure injectors. I found an old Ebay listing for the 2517031 injectors, which were also listed as "Crusader Package - Fuel Injector Tbi 47031". I did some digging and found these are still available new in some places, but I called MotorMan from Ebay, and he had them in stock. $250 for the set which was fair.
Lets cross our fingers that this solves it! If it does I guess I wasted $650 on a Diacom tool, but I am sure it will come in handy later!
Trying to be positive!!

Well sometime's the answer is right in front of you and you cant even see it. The 11's are the wrong injector's as all of the injectors posted and used aside form the 17's. Here's the answer all of the injectors are 80/90 lb injector's at 13 psi. Now the delco mefi system use's 30lbs psi...
i do believe that's a tad more fuel than is needed actually thats so much fuel someone needs to change there oil before firing it up again believe me its contaminated with gas. Now the 17's are rated at 45lbs at 13psi so when you push them with 30 psi the flow is going up just a bit...enough you should be a happy man..the only question can the standard injector handle the pressure.....id be willing to bet a cheeseburger and large fry's yes they can.
The tj17 injector runs across the entire line of merc using mefi
280hp; Model: LX EFI Gen+; All Engine.; TBI.
280hp; Model: 350 Magnum EFI Gen+; All Engine.; TBI
250hp; Model: LX EFI; All Engine.; TBI.
290hp; Model: LX EFI Gen+; All Engine.; TBI.
290hp; Model: 350 Magnum EFI Gen+; All Engine.; TBI.
220hp; EFI; All Engine.; TBI.
