there otta be some dude gettin 40 miles to the gallon the way they advertise mods:
intake + 1-2mpg
10k mod + 1-2mpg
exhaust + 1-2mpg
aih delete + 1-2mpg
pre pump + 1-2mpg
chip +1-2mpg
new improved cps + 1-2mpg
203 stat + 1-2mpg
wicked wheel + 1-2mpg
whatever, a chip is the biggest improvement, the other mods are to compliment the chip, or keep things safe. MPG is how heavy your foot is. I coulda got better mileage going to INDY by driving 65-68 and keepin the boost down......just one problem I drive 7 mph over the speedlimit. If they set it at 90............you guessed it. If I hurt my mileage by more than 2 mpg than maybe I would slow down, but my time is worth more than that to me.
I got right at 17-19 with 7-9 lbs boost, 10-17 on the grades, 2050-2250 rpm, 600-700egt's 800-900 grades, tranny at 125-135. I can live with that.
