Engine/Transmission (1994 - 1998) DDP stage III's w/160 pump

[BHuebner]

Talked to Ross at DDP and he recommended the stage III's for my truck. said i could upgrade to a hx40w later when ready. he called me back and told me i may need 181 dv's, said it might idle funny. what do you guys think??

I'm going to DDP tomorrow to have my injectors "cleaned". Hope to take some pics.

The story goes that if you want to run big injectors with a 160pump you need to upgrade the delivery valves, this goes for DD3's, DDP3's/4's, Mach4's, 370's etc, otherwise the engine may have a twitch from idle up to around 1100rpm, sometimes bigger DV's help sometimes they dont.

bigger DV's help smooth things out when i stepped up to 370's. keep in mind my stock DV's were 181's. now that i went with DDP's 4's, the engine runs even smoother. if only i could keep my foot out of it long enough to check for milage improvements

Would going to 191dv's be too big or just order the 181's? or is there such a thing runnin them with DDP stage III's. guess i could install the injectors 1st and go from there. (its just time and money ... . right!!?)
