How and why is an rv275 injectors supposed to get better mileage than stock injectors?

I definitely want to change this antique out it came on the truck when I bought it. 

May I ask why you're changing vp

1693 code, defuels,dies out sometimes. Bucks, sometimes doesent want to start after it dies in traffic dead paddle. Sometimes it  has great power sometimes a total dog.

Sounds more like apps, 216 would be for vp, I would double check everything before getting vp and having same problem. Scan with a good scanner for codes, make sure all grounds in good shape. Minimal ac comming from alternator, mine is around 0.03vac at idle with all accessories off and make sure you drove the truck first so grids are not cycling. I usually check mine after i come home and before I shut engine off. And you'll need a better volt Meter then a 10 dollar ones. Don't have to be top o gb the line but need to be able check in thousands like on below.

Damn it had it scanned at auto parts he said vp44was on it's way out new one gets delivered today. 

All I have is an old analog type tester. Electrical is my weakness. 

I hope you didn't buy vp from part store, just never heard anything good about them kinda like alternators, hit and miss. And how were they able to diagnose that I'm very curious, hunch or we're there codes that led them to it. Still there is always testing that need be done before condemning vp. @Mopar1973Man any suggestions

P1693 code just means there is another code present and need to use OBDII code reader. 

 

As for the Bucking and dying you need t oread the codes so we know what you got going on. As for the part store injection pump you can't verify if its been on a Bosch 815 test stand and calibrated after being rebuilt. I've got a listing of the shops that have Bosch 815 test stands.

No I got it from Industrial injection. 

Part store guy used code reader.

Write more information

Industrial Injection is a Bosch Certified rebuilder they do have the Bosch 815 test stand. 

How many miles on current vp

Now I'm waiting on my Fass.

Trucks got 113000

Give you a guide on VP44 longevity. Being I've reached 243k miles on my last pump. 

• Clean DC power - Make sure you under 50mV AC for good life span.
• Filtration - 3 micron filters are the best. If you can double stack is better like when you install the FASS leave the stock filter there and use a big line kit from Vulcan Performance.
• Lubricity - Bosch states you should have <420 HFRR fuel but all US fuel is 520 HFRR. 2 Cycle Oil is a good lubricant to add to the fuel.
• Fuel Pressure - 14 to 20 PSI is optimal. 

Thanks.

I always add 2 stroke to my fuel.

I was going to retain the stock filter.

 Explain  the power part for me please.

Just means no excessive ac output from alternator. Seems that a lot of us are around.0.03vac at idle, some less some more, if I rev mine up it can go as high as 0.1 it's a fail according to some, but I can't get it lower than that. Tried 3 different alternators, never had less than 0.028 measuring at alternator it self, not at batteries. So I'm calling it good, when mine did partly fail I believe it was around 0.1 idling. Ended up being just one half failed diode and wore out brushes with atmature. It still charged fine.

Kind of like myself going from Edge Comp to a Quadzilla it day and night difference in tuning. Technology has come a long ways for our truck since the release of the Banks Tuner. You might step over to the Quadzilla forum and take a peek.

I have been looking at the quesadilla tuners, like I said I don't want a race truck so how do you feel about the XZT box? 

 I don't want to wire tap, will it work with the rv275 s?

A non wiretap box and RV275's  work well together. You could probably go higher if you want too, but this combo works well for those not looking for big power. I was happy with mine but still had the bug for more, hence the Comp for me.

I really don't like them. 

 

When you had the time to custom tune like I've now got the grip off now. You don't want to go back to canned tune. Even my truck is not designed around racing at all. It completely designed around efficiency and longevity. So like my Economy tune is very very mild and ramps up slower and is smoke-free and the timing is set for optimal efficiency. 

 

Now like the old Edge Comp I had was OK. It did great for power and performance. But sucked for efficiency. Again comes back to the lack of control for fuel and timing. So you had to limit yourself back to stock or RV275 injectors to keep the MPG up and smoke down. That where my MPG switch came from was learning that the timing was over-advanced in the dead of winter killing the MPG number. Now my current tune compensates for that problem.

 

So like I'm currently running the Quadzilla Adrenaline without a wire tap. I've been tuning for the entire year now without a wire tap just to make the best CANBus tune I could like the XZT but it will be much better when done.

Ok that makes sense, actually I do want a race truck but can't afford it, can I still use my banks gauges.

I'll look into the adrenaline. 

Your Banks gauges are tied to the tuner if it is like my Ottomind. You will loose them. I replaced mine with Isspro. Just a cost of doing business. 

Yes I have an old ottomind box it came in the truck 

That's one thing I never liked about some of the tuners like Edge Juice and Quadzilla the gauges are included but at least Quad works without the gauges. I've always had stand-alone gauges. If I don't want to pack my cell phone I don't have to the Quadzilla still functions without a screen present. Now Edge Juice will not function without a screen present and very visible to a thief you've got a tuner. This gives my truck the kind of "stealth look" there is no tuner visible in the cab and less likely to be broken into because it looks like a stock truck with gauges that's all.
