little b, i to am having a miss, mine goes to 2200 then clears up. this all started when i pulled my large dvs out, replaced with stock 181's and installed my ddp3's, i will be putting my stock injectors back in to see if this clears up the miss, if not the next step will be to look at the dv's/plungers in the pump. i dont mean to jack your thread or anything but would like to give you some things to try.

definately try the stock injectors and i bet your miss will disappear, the miss you hear is the spray pattern being different by i think its 5 degrees on 3 of the 6 holes. therefore without marine pistons you will never make the truck run right and efficient. im not saying guys dont have trucks running 370's that sound "right" and seem to run smooth, but as far as running with the most efficiency and power from the engine 370's wont cut it with non marine pistons.
P.S. i too tried the 370's and city diesel DV's to fix the problem but after doing some research and learing the engine and fuel system better i found the real reason it runs bad. try a set of laser cut DV's and stock injectors and you will be amazed at the difference. pm me with any ?'s. also bumping the timing will help a little bit.

i changed the copper washers today help a whole lot now as soon as i give it a little petal it spools a little apicks up and smooths out but it doesn't smoke as much as i want it to i thought going with the bigger dvs and injectors it would roll the black but it doesnt the only thing i can think of is the pulsing the injectors are doing is keeping the turbo spooled better but what do i no it does have a lot of raw smoke when idling though thanks guys any input would be great
