help me mod up my early 99

[99PSD-White]

Hey guys I'm new to this diesel thing and i am learning a lot being on the org. I have a early 99 7.3L and want to get some good power out of it. It has 131000 miles. Right now I have a bad injector causing a my truck to shutter when underload at 1500 rpm or lower. Truck runs fine down the highway. On road that are 50mph I gotta turn overdrive off to keep the rpms up and keep it from shuttering.

Anyways I need new injectors and there are sooo many places I have found that make them. I have read that my truck has split shot injectors? Is the early 99 the only one with split shot? I want to get a stage 2 injector. But do I want single shot or split shot? I plan on getting a tw chip also. I already have a straight pipe and intake. I know if I get stage 2 single shot ill have to get a custom tw chip for the singleshots. what do guys think I should do?

Have you check or tested anything to indicate you have an injector issue? A "shudder" does not mean injector issue... Most PSD injectors will last 200k or better.

If you do go injectors single shot is the only way to go. You do not want a modded split shot.

Ya I'm gunna have it tested very soon. Within the next two weeks. What else would cause this shutter probem? Tranny seems fine.

Tranny, UVC harness... lots of things... I very much doubt its injectors...

I have seen the torque converters do the same type of shudder. Have it scanned before you do anything. If you check out my sig, mine is an early model. I got all my stuff through Beans Diesel, they really helped me out.

hopefully ill find out when i get a buzz test and contribution test. My dads buddy used to be the head engineer at ford for all diesel production. Hopefully he will be able to tell me a thing or two.

well i have been reading alot of stuff about different shutter problems and i came up with it eaither being the injectors, uvc harness or TC. i hear the 99 have had a problem with the tc shutter and flex plate or something.

also another problem is when my truck is cold and when i start it in the morning i get a crazy idle like its got a high performacen cam. when i start it i usally just put slight pressue on the throttle and the erotic idle goes away.
