new injectors now has rough idle?

2004 silverado 2500hd with lb7 duramax. it was running fine but the injectors were going bad so I replaced all 8 with bosch remans and new hp lines. now it has an idle shake gets worse till 1500 rpm then the shake goes away. changed the stock fuel filter to a nicktane then back to stock to see if that was the problem it seemed to get a little better but not where it was before the injector swap. also loss of power on the low end once it catches up it is fine has few second hesitation it dosent stall out or try to it seems that it is trying to catchup with the demand for fuel. the frp reading are all over the table and the last wot only reached 18000 psi. my thoughts are bad cp3 pump or fpr.

you said it was running fine, but had bad injectors, now you replace them with more bad re manufactured injector, in order to troubleshoot you'll need Tech-2 scan tool.

just took it out again last time i ran fuel rail pressure it was in park. took it out on hwy got 24000 psi pretty regularly with wot.

im going to have the balance rates tested but i dont think its an injector. they were remans from bosch not one of there affiliates. also i have no smoke or fuel in the oil.
