there is no way of getting them any closer than that, when you buy them from other places he seta them as close as he can get them which is within 100psi of each other,
the reason you cant get them any closer is cuse there is not shims availible to go any lower in psi, if someone were able to make the shims then it could happen

From a mfg standpoint 5% tolerance is pretty high, I would expect better from a company like delphi.

Great info yet again! I'll have to look up this typ4 on Oil Burners.... I wasn't planning on doing the injectors yet, only at 126000kms now but they're certainly in the books. That being said though, that seems like a great price for the return line kit, viton orings and NEW injectors. Maybe I'll do it all at once! I am curious about that 5% tolerance thing though.... wondering if anyone can privide any tolerances from either a manufacturer or something as a comparison......

Yea that 5% bugs me that seems way high for matched injectors. I may be thinking wrong here, but if you bought 20 sets and can't match them closer than 5% I would be looking for a different manufacturer. I would like to see the manufacturer claims and specs. Matching them has been going on forever for years in the diesel world I just do not want to belive 5% is the best you can do at matching them, bit I could be all wrong.
Dave S uses Dps stage one and has been satisfied with them. The one and only time I was on oil burners some one claimed they were junk, because of the way they were modified. But in my mind they have been proven by Dave,so who knows.

star and warozz you need to do your homework before calling this gent out . 5% is not acceptable but thats what Ford gave us to work with , injectors that are set with shims.
Sounds easy, just get other shims- uh huh good luck its been looked into quite alot by people more knowledgable than myself. This is I believe the stumbling block that has kept crossbones2 from 'super tuning' one of these motors with his glow plug method. Other style injectors have a dial to fine tune the settings, makes sense. shim style injectors are crap and meant to be thrown away and replaced every 100k. I got the old injectors in my Isuzu set within 3 psi of each other because they have a dial, with shims getting within 50 psi is considered nearly impossible even by experts.

Nappy I am not calling any body out period. I would like to know what the manufacturers call allowable tolerances. That said if they are 20% and you are dealing with high volume sales and buy say 100 injectors at a time and pop test them all to match them. You should be able to get very close as far as matched sets goes some sets may be as far as 20% different as other sets, The bigger volume you have to work with the closer your match is going to be without ever reshiming an injector ever.
That said if your reshiming them you can take 8 injectors and get them very close but probably the time involved would not be worth it from a marketers standpoint.
