Well I yanked my RV275's back out. They started to misfire at idle again. Looking them over and the nozzle where only lightly sooty and the nozzle holes were very visible even to the naked eye. So I already talked to a shop in Lewiston, Idaho about retuning hem back to pop pressure. Like I told him I found injector with a wore shim and I'm pretty sure this injector is my problem. So I'll report back what I find out when I get them bench tested.

Back to injector talk, just popped in some DAP +60 HP injectors last night...so far so good! Even without a box or programmer...yet, what an upgrade! I was able to light up the tires, quieter idle, smoother idle and acceleration and she pulls a lot harder now. Faster than my old 2500 hemi! As soon as my limited member status is over I'll post some pics of the new DAPs vs my stock gunked up injectors...just over 208k on the old girl.

Glad to hear you upgrade was worth it. I would suggest grabbing a module at this point and tossing it into the mix and then you'll gain the timing for the MPG's and the control over your fuel. As for the limited membership it will be gone in no time...

Is this a common problem with the RV's or just an issue you've been dealing with personally? I just bought a set of genuine Bosch RV's from DAP. Hopefully I don't have problems with them.

Sure hope not! I bought the same thing and a new VP from DAP and so far love them but then have less than 5k on them. Anyone have any ideas what to do with the old stock injectors? They have 140k on them and were running fine but wanted a bit more performance. Thx, FT

You could send then into Vulcan Performance and have them re-nozzle, pop-test, and flow matched. Or really cheap just send them in and have them pop tested and tuned.

Mike, Thanks and glad I got them back.Thx,FT

Said I'd post a pic of old gunked up injectors vs new 60 HP ones...very happy so far. Can't wait to get my edge comp!

How many miles on that set? Mine had 144k when changed out... FT

I'm guessing they're from the factory, so over 208k...and seemed to be running fine

As long as you can reach over 1,000*F for a few miles of heavy towing you'll clean those old ones right up. But you'll enjoy your news ones as well.
