mpg
numbers in sig and with 4.30 gears, I got 23 mpg on a recent trip to Houston from Hammond Louisiana. I cruised at 80 mph most of the trip.
In the city , I put 167 miles on the car while in Houston and averaged 18.5 mpg.
Oh yeah! A/C blowing on max the whole time

W/ your mods, I'm thinking your milage isn't due to a poorly running car. 
My first thought is to say you drive ...... spirited, a little more often than you should. 
I hit 27.9 MPG coming back from Rapid 6hours at 75mph with the AC cranking. Usually about 18-19 in city driving. It all depends how much you press the loud pedal.

well are we talking in town or on the highway?
in town my 388 is measured more in gallons/mile than miles/gallon (might help if I would keep my foot out of it but oh well.... )....
on the highway it gets about 22-24miles/gallon (6 speed with 3.73s)
my old 346 with a TR224/224 made 400rwhp/385tq and I was able to go about 425miles on a full tank (ran it almost dry) ....
it's all the T56s 0.50 6th gear........at 80mph I turn 1950RPM with 3.73s so I am going a long ways/quick for not a whole lot of RPM (which = fuel).......autos don't have that ability so they tend to suffer more....

cool.thanks for all the info.if i can atleast get 20mpg. when i do the swap in the s10 blazer. that would be about 400 a tank. with a 20 gallon tank. that would be nice.it got 25 mpg when it was brand new.
don't forget to think about the weight difference of the vehicle, if that's your reason for asking.....plus a bigger tank, more gas, more weight....little things add up......just a little heads up

I've seen 30+ mpg on the highway and usually low to mid 20's in the city depending on how heavy my foot is in my all bolt-on M6 Firehawk.
My truck gets roughly 7 mpg in the city and 18mpg on the highway. The truck is basically a 5.3L LS1 and runs on regular gas. I attribute the sucky gas mileage to the following: Heavier, less aero-dynamic, automatic transmission, and overall larger vehicle.

I usually get around 15 MPG... but I think that's pretty good for getting on it a lot.... HP Tuners hasn't helped either... I find myself doing more "Test Runs"
Oh well if I wanted mileage I'd run out and buy a civic hybrid tomorrow
