do tunes affect the computer's ability to monitor mpg?
when you get new injectors and a tune, does the computer take this into consideration in calculating mpg? i assume it would, because the computer has to base how much fuel goes in order to function properly. not sure if it were to base mpg on stock injectors, hence the ?

So to answer your question, while the computer doesn't necessarily "adjust" for new mods it doesn't have to.

Not sure if you can adjust this in the ecm tune or if the numbers are crunched by the bcm.

I have gotten 41 MPG
When I had around 10,000 miles on my 07 SS 2.0, I was out high altitude driving about 85-90 MPH and was getting 41! I have a video from my cell that I saved. I will see if I can download it and post it. I think I was listening to Tool!

2 years ago i drove down to Carlisle PA and averaged 37MPG with a full truck of car detailing stuff and suitcases. 65MPH and cruise control all the way!!! Made it there and still had about a 1/4 tank left didnt fill up until the all-gm nats were over and filled up right before we came home.

Ok You stated above you did 372 miles and had an eighth of a tank left. So well say you had 2 gallons left of 13 the tank holds.
372 divided by 11 = 33.8 mpg
372 divided by 11 = 33.8 mpg

that's true but it doesn't change how many miles he made it on a tank. I've done 700km's on a tank before on a roadtrip avg speed was 120-150km car seems to like going 120 alot more than 100

So this weekend I went for a drive into the mountains with my girlfriend to Banff, AB.
The trip was 599kms (372m) round trip and I did it on 1 tank! (see pics below) For about 500 of those kms I was doing 120kmph (75mph) and the rest was bumming around Banff in second gear because thier speed limit is only 40kmph (24mph)
My mods are 2.8 60# injectors, exhaust, etc.
So here's proof of what a tuned lsj can acheive
*notice how I still have 1/8 of a tank left!!
6.0L/100km is 40mpg
Before I got into the city I was averaging 5.7 which is around 43mpg.
