DD3's installed

A HUGE thanks to BigK, Nailbender, and DEZLPWR for coordinating a last minute dual injector swap before the PDR event!! I went from stock injectors to 3's.....WOW what a difference!!! I'm all smiles!!! ;D ;D ;D

One thing I did notice is my fuel economy actually increased with larger injectors. With EZ only and stock injectors I was getting between 16-17 mpg. My first tank with EZ and 3's I got 19.1mpg! That tank included playing with the fueling box, the go pedal, making smoke, cruising between 60-80 on the freeway and a dyno run. Is it common to get better fuel economy with larger injectors? I figured it would decrease the way I like to drive.

Diesel Freak,
It may be awhile on the turbo. Remember I am a student at this time. Funds aren't as available as they once were.

Re:DD3's installed

PB&J sandwiches. I'm in college right now and I know what it's like having tight funds. I'm currently working at McDonald's (don't laugh) earning around $100 a week. All that money is going into a savings account that I created just for my truck. Nothing else. ;D

Re:DD3's installed

Been checking for leaks? Any?

Numbers seem a bit low to me, also ???

From the rumors that I hear, we need to get on those fuel system upgrades.

I'm gonna need them soon, too

Inside projects are made for winter. Or is it the other way 'round?

Time for some more Aeroquip fittings and SS braid.
Don't tell my wife
Got an idea for a pump to try. Looking into it now.

Soon as the rains come en masse.

Re:DD3's installed

Eric,
No leaks so far. I've checked several times since Fri. Dry as a bone. 8) Thanks again for your help.

As far as numbers go there are lots of variables and differences between Dyno-Jet and Dyno Dynamics. I plan to get back on the rollers in the near future.

I have all the lines/fittings to do the fuel system. Just let me know when. ;D Keep me posted on the pump.


Nathan

Re:DD3's installed

Nathan are you checking your mileage with the overhead console. Not trying to burst your bubble but larger injectors trick to computer into higher reading. Check it manually also.

tlea,
My truck doesn't have an overhead computer. I figure mpg with a calculator and my speedo is corrected with Tru-Speed. 8)

Re:DD3's installed

Don't want to forget to thank Steve and Nathan for keeping us all from dying of thirst or starving 'round here. ;D

I think that Dan, or "brand F" neighbor, got a bit of an eye opening

My truck, with 275's alone & no boost over stock, edged his "chipped" and similarly configured F, albeit on the SOP-meter. I have less $ in mine, but his blood runs blue, and we're both happy. That's what's important.

Stuff will be happening here soon.

Anyone else up in our area that's interested?

Hi Nathan,

I was told and it has been my experience when running DD3's and larger injectors to consider the use fuel additive to help keep them from carboning up. After I ran mentals for one season they seemed to run like DD2's and yes I varified this with 1/4 mile times. After taking them out and having them cleaned the following weekend the truck was back to normal track times.
