Never really cared much about it before, but now that I have my speedo hooked up and calibrated and can calculate my mileage its looking terrible at best. I haven't been able to get above 10mpg usually 6-8 with fun throttle input. All the tanks calculated have been stop and go suburban driving (small town ish?) Just curious if this is normal or somthing to be concerned with!
99 vette ls1 with fuel injected magnacharger set up (8lbs around 480hp)
th400 trans with shift kit and 3200 stall converter
9" rear with 3.50 gears.
I'm thinking between the three speed and large converter I'm loosing alot of fuel economy. I have a smaller converter I could swap in if I was curious enough
Would the big 9" Effect mileage significantly vs a 12bolt or 8.5?
Another thing is the car hasn't been dyno tuned. been running on a mail order from Steve Williams (FROST) Which does great. Runs fantastic, plenty of power, doesn't smell rich or idle abnormally. I have no codes in the pcm, fuel trims are normal and o2's are switching normally. Any idea's? I usually daily drive this and I'm just curious as to what you guys experience for real world city mpg's
