I tow, and plow and sometimes the truck might idle for a few hours at a time while out on a job. 

 

I have DAP 7x.010 SAC injectors that at the time were new body injectors circa 2013 and they have over 200k.  I pulled one for a pop test and it was dripping slowly when closed so it's time for a replacement, also the truck is showing tired injectors by idle hazingl more and more with time.  I'm hoping to get some expert opinions on the matter to replace.

 

I have a truck built to make power while towing.Quad v2, converter is a little looser stall than stock, I've gone down from a s364 to an s362 that behaves well. SOVP, the rest is pretty normal components.

 

Given what I do with the truck, I hear VCO injectors might not last with long durations of load like towing interstate for hours and hours or idling for hours.  If anyone has lifespan experience in a similar work load I'd like to hear about it as well.  If    @dieselautopower has an opinon on what I should run and what BAR pop pressure it should be for good towing and less idle haze I'm all ears and will hop on the website and buy them today.

VCO's for fuel mileage and cleanliness.  SAC's if you don't care about either.  The advantages and disadvantages increase as the injectors get bigger.

 

I currently run 7x.010 VCO's but will be switching to 7x.012 SAC's in the future since the truck is just a toy now and I don't give much thought to fuel economy or smoke levels.

The SACs perform fine on the road, they make power and don't smoke much thanks to the tune in the quad.  I don't expect perfection but I have a good combo for fuel control and it gets plenty of air.

 

Fuel mileage is a thought, I recently put this truck back into full time service after throwing the wallet at it from a few different angles and really should get something in return as a benefit. 

 

I'm also aware I need to make changes to the quad tune to go from sac to vco.  I am leaning on getting VCOs and then having the SAC injectors gone through and put away for a rainy day.
