Highway RPM seems high

I have a 2005 DC 4x4 Tacoma 6 speed that runs at around 2600 rpm while doing 70 on the highway. It seems like that's where the motor feels comfortable but, I had a 2005 4runner automatic that rode at around 1600 rpm on the highway. I was thinking that the six speed would have gotten me better gas milage and lower highway rpm... My dad's 2009 Automatic rides around 2000 from what he said. Is that high of rpms normal for the six speed? I tried to search but came up short so any help will be greatly appreciated!

 

Nobody with the six speed has any experience with rpms on the highway? Just wondering if it's normal...

 

You should be in the low 2000s if you are only going 70. I'm usually at the mid 2000s going 80 in my truck...but I'm auto. You should be lower though

 

What could be causing this to happen? Can it be tuned or gear ratio changed? I think the guy I bought it from used it to tow his motorcycle.

 

It seems to be fine, I just want better gas milage....

 

I appreciate the help. I just wanted to make sure this was normal. Thanks again!

 

yep chris beat me to it. It's different in these trucks how the auto is rated for higher mpg than the manual.

 

If your more interested in gas mileage than towing power you could always have the rear gears swapped out.

 

Actually you would need both front and rear changed. You're looking at over 1G$. I would say leave it, it is what it is....

 

I was thinking about this thread as I was driving between Pensacola and New Orleans today. I was cruising @ 77mph and 2600rpm...so I vote yours is normal.
