I Have pacesetters race style headers with tsp's x-pipe duals and a 3400 fuddle stall, i drive normal, rarely ever get on the gas, but i'm getting about 9 to 10 mpg...is this normal??

If its not what are somethings causing such a low mpg?

Thanks guys, i hate gas...

9 to 10 miles would be normal for a cammed car.Check your tire pressure,air filter and change your fuel filter.

I drive mine like I stole it, with similar mods and M6.. I get around 19-20MPG, 25-28MPG if I'm on a trip.

I Figured 18 MPG would be more realistic

yea, thats low. 15mpg would be what I would say, and thats on the low side

What could be a problem causing it to be that low?

I wouldnt know much about what can be causing this but these are just my suggestions....

New Air Filter, New Fuel Filter, Fuel System Cleaner (I use this every 4k miles as suggested). Change Oil & Oil Filter, get the kind that is said to help with MPG.

I know a bad MAF sensor will cause a drop in MPG, but that doesnt seem to be the problem here. I cant think of anything else....

The stall converter. I have the same problem i get about 13 miles to the gallon with highway and city driving.

Has your car been custom tuned to the converter? What gears are you running? When was your last plug change? FF change?

I don't buy the whole well, 15 sounds right.. etc..

I am running H/C (236/242 .610) with a 3600 stall, bolt on's... I average 19-20 mpg on the highway with an occasional race or two. 270-300 miles on a tank of fuel.

I'd get a good tune, change plugs,wires,FF,AF and get back with us in the morning.

Check for an air leak into the intake that the mass air flow senor isn't accounting for. My Head/Cam Stalled A4 gets about 15 1/2 around town and almost 22 highway with 3:23's which is almost the same as it did stock. But after I did my Head/cam install I had a vacume leak around the AIR fitting at the front of my intake which was causing me to get about 12 MPG around town and 16 Highway.
