    Did any of you guys try using a GPS to compare "real" vs. speedo. Can also use same technology to compare odometer.

    How difficult is it to regear from 3.73 to 4.10 on a 2nd gen? My mpg sucks with 33"s because most of my driving is done in rush hour traffic each week.

    looking to maybe drop a turbo kit to my 1st gen 4 banger tacoma. (2wd), i was wondering if re gearing is a good idea and if it will help performance and if there is a certain gear set up i should be looking at. my truck is also lowered.

    So does this mean since I am running 275/65/18 I am actually getting better mpg than I think? Would that also mean since I am at stock gearing, my speedo is registering "less miles" than it should be?

    Yes. If you go to tire size calculator under the mods&tutorial tab at the top you can plug in new tire and old tire size. It will tell you the difference in revolutions per mile.

    I don't think it's a good idea to regear for MPG. The savings is miniscule vs cost of gear installation.
