Why is no one honing their injectors? I had mine done 5000 miles ago and have had no issues. The guy who did it is a Dodge Tech that specializes on diesels. He said it is the only thing that they can not detect. He said the sequensing of the injectors is not an issue yet. When he was a Cummins school he messed with the sequence and the ECM didn't even know. I am just surprised that no one is doing this instead of using a chip or programer that will void warrantee. A 70 horse hone helped my mileage as well.

Yeah, that sounds awesome if you got 70 Hp out of it!

Did you dyno your truck before and after on the same dyno???

What I mean is...how are you sure it's a true 70 Hp?

How much torque did you gain?

Can you "safely" hone them larger to gain more power?

I had mine done in Kamiah Idaho. The guy does it on weekends in his own shop. It cost me about $750 to have it done. He picked up my truck on Wednesday and did the removal, hone, ballance, and installation and I picked it up on Sunday. I don't know what he would do if you were unable to get the truck to him. I assume you could send him injectors and he could hone them and send them back. You could also buy new tips for one of the advertisers on the site and do it yourself.

I did not have it dynoed, but he said based on the flow rate it would be 70 horse. I can pull hills 10 miles per hour faster than before when I am loaded. I regularly gross 25000 lbs when I haul and he said I would not have to worry about egt or anything.

I looked up a local place that does Extrude Hone. They said a 10-20% hone is about $240. Just need new copper washers to replace the old ones.
There was an acticle in one of the Diesel mags a couple months ago.
I haven't done mine yet, but plan to after I get a lift pump and modify my CP3.

I wonder what 70hp injectors will do to the DPF since it is adding fuel all the time. TS says not to run the MP-8 on 100% if your going to idle much or driving in town. Wouldn't the injectors do the same thing to the DPF as the MP-8?

Do they guarantee against breakage...like FearTheDeere said, honed stockers are prone to splitting under heavy abuse!?

Okay, so does anyone just think the DDP 80 HP nozzle set, is more worth it?

If it costs $750 (at minimum), to have them honed...

And it only costs about $900 for the DDP nozzles, that are completely NEW and CNC'd to prevent splitting.

So, if you ask me...

I think I'll be going with the DDP injectors, because they offer a warranty against malfunction...plus it's a completely new nozzle.

And, it's not much more in price!!!
