im getting about 140 mpg just rebuilt engine lt4 hot cam and tune is there something im missing? any help would be great. thanks

 

140 MPG, and the complaint is??? With the same set up I was averaging 25-27 MPG on the highway. lol

 

sorry 140 per tank and 20 gallon tank

 

Semi accurate way of measuring fuel mileage:
1) Fill tank to top and record odometer reading.
2) Drive around till time to gas up again. (down to around 1/4 mark)
3) Fill tank to top again. An this time record the amount of gas needed to fill up. (gallons & tenths)
4) Record odometer reading again.
5) Subtract first odometer reading (step #1) from second reading (step #4) and record miles driven.
6) Divide the number of miles driven (in step #5) by the number of gallons used in step #3. This will give MPG.
7) Repeat above procedure several times and get average.

 

i didnt know there was a 20 gal tank available for the camaro. mine holds 15 gallons. even so 140 miles outa 14 gallons is only 10 miles to the gallon. is that freeway or city?

 

i think your right, im getting that kinda milage too
just looked in alldata it say 15.5gallon capacity for a 94 unless others are differant thats what it is

 

im at about 20mpg

 

wanna trade, lol

 

I get about 18-22 depending on how I drive it. ('94 Z28 with A4).

If you are only getting about 140 miles per tank, something isn't right. I would pull a couple of the spark plugs and see if they are black, indicating a very rich condition. Then, I would double check to make certain that I got all of my sensors reconnected. Also, scan it for any stored codes.
