Word. Some powerstroke must have been jealous and slipped a roofie in your trucks drinking system.
The cheap route usually is not the cheapest if you know what I mean.

Oh i hear you loud and clear! Can someone more intelligent than me give me the run down on the affect of extremely unbalanced injectors.
Did you test your injectors while you had them out? What was the mileage on them when you had them tipped?
My very first set of oversized were a set that GM did on a replacement under warranty and had 12 k miles. I thought they should be perfect to have done. I sent them to a shop that does balancing as extruded hone did the nozzles for them. They were 45 overs. They did not last 30 k miles. If I had known if Exergy then I wouldn't have had that problem. I even had the extrude hones tested by Exergy to see how close they were. They did not test very well at all. No were near the +- .5 percent like they should have been. That is the spec that extrude hone says they do. Long story short I spent more going the cheaper way and I spent a lot more than just the nozzle flow like going directly to extrude themselves.

No I didn't test my injectors. I'm not sure how many miles are on my injectors. Bought the truck at 170k miles and now has 220k miles so idk if they are original or not. All balance rates are -/+1. The tips I bought off the forum. They had I thin around 5k miles on them.
extrude hone is available to everyone through Jim at Get honed, while this is very convenient to many it also has everyone talking bad about it... but the fact is the best of nozzles are extruded at one point... everyone has their own way of making a tip flow how they want... for example many nozzles are tested by the 3000 air psi in a tip for flow... while this is a ok measurement it also doesn't quite stand true to the hydraulic measurement that is done at per say 26,000 that it would be operated at....
large nozzles are first EDMed then honed to nock sharp edges down... everything flows better over a radius...
Exergy extrudes their own nozzles right on sight.... everything is extruded up to 100% over.... then they would edm first followed by extruding... hands down the best way to make a A+ nozzle... many others also use this method.
The whole balance rates thing isn't on how your nozzle was done. Its on how it was actually flowed and balanced after being built.
nozzles are generally 1-2% matched then the body's are then balanced out.
Jim at extrude is very good at what he does and their is a purpose for what he does. I wouldn't be bashing to hard on extrude.... and definitely not on one of the places that has been in it for so long and that many company's most of the diesel market swear by but would never guess use them......... just food for thought....

My list were lot meant in any way to bash Extrude Hone. It was more so to explain my experiences and to have a complete check of everything as a whole. The injector works as a unit not as individual components.
