Pete, I just lowered my IFR values today after doing some reading and talking with a few guys on the gto board. Hopefully I'll get out to do some logging tonight and see how they look.

May I ask how you are measuring fuel economy before and after? Through the DIC?
If through the DIC, have you ever wondered where the DIC gets it's info and whether that is editable or wrong?
DIC? Digital readout inside speedometer cluster is what im referring to. would that change with new injectors if all other data was entered into computer to account for them? My 04 GTO will display instant or average or fuel used which also resets a trip anytime the avg or fuel used is reset. Ive divided trip distance by fuel used and it has come out to very very close to what it displays as average fuel ecomomy. i could do it the old fashioned way by adding fuel at pump and dividing by a trip of mileage i suppose.

DIC = driver information center, so yes, the digital readout. you might ask yourself where it get's its calculations and if maybe that algorithm is now flawed....
i suggest a manual-at-the-pump calculation is a good place to start, but it doesn't sound like you have anything to compare it to, unfortunately.
Very possible i suppose but it seems that others who have added other injectors are not having issues with a false DIC reading but ill check into it.

Yep, you here it all the time. "I have a huge cam and heads and 500 rwhp and now I am getting 29 mpg on the highway" BS. If it was that easy, the car companies would be all over it. Just do the manual math and see what you really get.

Why is the data listed here different than what is on Banish's dvd? I thought 43.5psi was the rating not 39.15psi. Using 39.15 gets the scaling closer though.

They could also utilize the lean cruise on models such as the 04 GTO but its not emissions friendly. More compression and easier breathing and less about emissions you would think would make more efficient power and likely better fuel economy. But I could be wrong. I know the EPA is pretty strict in their fuel and emissions ratings these days too. You would think if they really wanted good mpg all cars would have a small turbo but i know cost and reliability could be an issue there.
I'm in no way saying a cam will increase your fuel economy esp a big one just wouldn't make sense to have a loss of 3 mpg with new quality injections installed and tuned correctly. I never did the old fashioned way of checking the mileage with the old injectors either so it could have been off before
My dads 6 speed c5 vette is nearly stock and got 29.5 mpg avg highway cruise control 72 mph on a 5 hour trip, 1,200 rpm just sips the gas i suppose lol
Thanks so far guys ill be checking it out the old fashioned way

My computer is a liar!
Did it the old fashioned way filled tank then drove on highway babying the car 1,3,5,6 easy low throttle shifts and setting cruise at 70 mph for a bout 30 mins odometer and trip say 25 miles
Pulled into gas station to refill the tank. Car stated 1.25 gallons were used and gas pump said .96 gallons were used(topped off tank till it almost came out fill hole each time)
Computer average was 19.6 and old fashioned calculation was 26!
I will be testing with more mileage and fuel use and see what happens but good news for now is i didnt appear to loose fuel economy at all! Lean cruise is coming soon! =)

You can calibrate that you know. The process is in your owners manual.My computer is a liar!

For the US version of the Holden Monaro (2004 Pontiac GTO) i dont see how to calibrate it in the US owners manual...just how to reset trip and avg fuel settings like i already know how to do. hmmm actually it can be calibrated with HP tuners ill look into having it done thanks =)

Ford uses a working pressure of 39.15psid (2.7 bar), Bosch typically rates their injectors at 43.5psid (3 bar). This is why you'll often see two different (but close) ratings for the same injector. The data sheets I included in my DVD account for this slight difference.
Any error in the fuel mass estimate in the calibration WILL skew the DIC's reported fuel economy. As others on here have suggested, the best method to monitor your fuel economy is usually just to look at actual gallons at the pump and miles driven.
"Why is the data listed here different than what is on Banish's dvd?"
Look at what year it was posted...
2008.. What's your point.
Greg has worked on the data since 2008, the data listed is wrong because it is old.
That data was from the manufacturer. Pretty sure the injectors didn't magically change over time.
thats the information that ford provides on there website yes but that is not what goes in gm's tables at all.ford uses complete different setup example those injectors in an ls1 flow about 52#s

Well I'm pretty sure mathematics concepts haven't changed in the last two years. Yes its Ford related data. But its not hard to convert for GM application.
here is fords sheet
