3dformula, you either have 2.73 gears or your speedo is way off.

I guess I could check it. It is not like I have tried to make performance improvements on this car, it's a driver.

guys, GUYS come on... listen ,here it is in a nut shell..... yes if you play musical gears with a street car that you drive that makes less then 350 rwh, seat of the pants can definitly get fuzzy. but on a car that makes close to 500 or more on the track fine tuned...... gears are EVERYTHING! a car setup up squeezing everything out on the track to run 6.00's in a 1/8th with 3.73's wont like a 3.42 change. so its definatly not that DRASTIC in close to stock street cars......its all about planning ahead though.......so cant we all just get along

3.73's are where its at!! I DD my car and it kicks *** of the street and strip. Haven't really noticed too much of a mileage drop though.... I'm happy!!
