Matt's tunes are really clean and he prides himself in that. I was surprised going from my Diablo Predator to GH tunes how much cleaner they were!

I've been on the fence for awhile now whether to do 160/175/180 with 80% or 100% nozzle. At one point I was leaning towards 238's detuned, but it just seems overkill, but Matt did say he could tune them well with 80% nozzles which seemed small for that many CC's.

 

I looked at Unlimited diesel because of the warranty but from what I have read they seem to have a lot of issues. So I'm probably going with either Full Force or PIS

 

Uphill, starting at 50 MPH, ending at 80 MPH, never dropping out of 4th gear. You can see a puff as I rolled into it, but no contrail.


Cody tweaked the fueling after this video, and the puff is not as dramatic. There is no escaping a puff when you get on it with big nozzles... unless you really power down the tune.

 

Not all of us are lucky enough to have Cody tune out trucks. I would love it.

 

The only injectors I will run are Performance Injection Systems...

I've run nearly every builder out there. Nothing tunes easier, runs cleaner and produces more HP per rated CC then P.I.S...

The 160/30 injectors will produce 400rwhp, nearly smokeless, without dozens of tuning revisions time and time again...

If you want a working mans injector, that anyone can run, the 160/30 is the one...

Cody and Curtis will say different, but they also tweek tunes over and over and over again.

People I deal with want the right, working set up the first time...

My Wifes excursion runs 160/30's with tunes right out of the box. Zero issues.

 

And the 80% nozzles are only 100$ more..
Seems like a great value for NEW injectors..
I am still in the air about buying either 30's or 80's.
My truck is a PMR.. But 2000 series donor motors with low KM are easy to come buy and fairly cheap..

Sure sounds like the trans kicked down as soon as you pushed too hard

Its not about the cost...

There is simply no reason to go to an 80% nozzle with a 160cc injector. You can empty a 160cc injector, with a normal, limited PW. Sure you can do it faster with an 80% nozzle, but you gain nothing, but the opportunity for more smoke.

I have at least 20 sets of 160/30's out there, all running box tuning, most towing 75% of the time or better... Happy campers!

 

Sometimes there is conflicting info floating around here, making the decision even harder.

Here is a thread I just found that has alot of good info if you take the time to read it...

Choosing The Right Injector

 

LOL... Have not been to PSN in years.

 

I recently installed a set of NEW AC160 stock nozzles, purchased through Riff Raff. They have about 5000 miles since i installed them 2 months ago.

I made a comment on a previous thread about me switching from Swamps 175's and actually liking them more than the these ac160's. I'm sure the tuning has a lot to do with it, and i've already received two batches of files from GH with no luck. They just don't run as clean as my 175's did.... idle is not as crisp either.

Would going to 30%-80% nozzles be too expensive?? I guess i should have just bought them with one of the aformentioned nozzles already installed, but didn't do my homework correctly.

After spending a pretty coin on rebuilding the engine i am kinda on a budget.... jejeje

 

Shoot me a message, I'll get you some tunes to try...

 

At what point with injector size do you need to upgrade the HPOP? I think I will email PIS and ask them there recommendation I only wanna do it once.

 

The point that you need to upgrade your HPOP depends upon the health of your HPOP as well as injector capacity and nozzle size. If your HPOP is able to maintain about 2600+ psi at WOT on stock injectors on a "stock" tune, a tune can cause the HPOP to perform poorly, then you have a reasonably healthy HPOP.

If it is maintaining that pressure then you could safely try the stock HPOP on either of the injectors that you are considering.

I would call P.I.S. and personally talk to Tim one on one.

 

A stock high pressure oil pump SHOULD be all you need for most injectors depending on who tunes for it.

The big push for aftermarket oil pumps came from a gross misunderstanding of the relationship between the injectors (variable) and time (absolute). I beat on a set of 250/200% regularly and NEVER see more than 40% duty cycle when pushing it; with a 275k mile oil pump to boot.

If you want to needlessly replace things before knowing for sure, have at it. At least try it first since there is no reason to ever "need" a different high pressure oil pump with 160cc anything as long as the person tuning them understands what they're doing.
