The tbird finally got a shot! And now a 2nd one!

well one thing worth mentioning is it said like 15.8 three days ago, now the last three days Ive had final exams. Last day of classes was last weds so mom and I moved all my  home then, and I drove up for the finals. Each day, 30 min there, 30 min back, 90% highway at 55-65 mph. Its now at 18.9.
 
The one thing that makes the meter a little inaccurate is if you're in accessory mode, switch cranked forward just before you turn it to fire 'er up, and the dash is all lit up, the meter takes readings of 0.0!!! So you watch your avg MPG reading go down and she's not burnin any! :hick:
 
So for that reason I want to do the calculations with my trip-odo. etc. to verify it. But we'll see, I've watched you post about your amazing gas mileage and I sit here wondering why mine's so poor. Makes me wonder if everything went right. That 0-60 time I got sways me the other way though, I guess I really need to find a dyno and get the real #s to be sure. Whatev doesnt really matter that much I guess Ive driven the  thing for just about 2 years and I've put 6000 miles on it. :D  So $5/gal gas? Bring it on I say.

Mines getting about 15 mpg in mixed driving. I have a 3.73 gear so at 70 mph on the highway I'm turning close to 3,000 rpms:hick:

My car got 300 miles a week since I started college back in August so I'll stick with my <1500rpm highway cruising.  Hopefully once I secure a job close to home, it wont be that bad.

Btw, there's a car show near me this Sat so I plan on takin the Tbird up.  I wish I could have the exhaust done before hand, but oh well.

Not possible unless you are not using O/D(then it should be more)... You running 22" tall tires??? That would do it...:hick:  My RPM's at 75mph with 3.73s is approx 2500...
