Hypertech makes a Speedometer Calibration Module if you want the speedometer to be correct.

Even though there is only one size difference between the stock Rugged Trail tires and BFG AT KO tires, they are very different. Take a look:

I trimed the skid plate just to be on the safe side. Here is what the tpms sensors look like.

I put a spray on bed liner in my last truck and liked the result so I did it again. I like it much better than the plastic inserts or a rubber mat.

Now I'm going to research a K&N air filter. On all the motorcycles I have set up through the years, I always opened up the air box, rejetted and opened up the exhaust. Only doing one thing, like changing to a more free flowing air filter without doing anything else, doesn't seem right but I'm open to suggestions.

I'm not looking for more power but I would like better gas mileage. I was told today that just changing to a K&N air filter would improve my gas mileage by 1 1/2 MPG. I'm not sure I believe it.

Looking good on the new shoes 2on2off. You might want to consider throwing the Volant into the mix for a CAI, especially since TTZ members get a special deal directly from Volant. If you think you might be interested, email Danny at Volant (danny@volant.com) for a member price.

I looked up Volant and couldn't find a CAI for an 09-2010 for a 5.7L motor. I'm sure there must be one since you have it.

How do you like it and have you noticed any change in MPG using it?

I know Danny (with Volant) said it would work on the 09 Tundra 5.7L, and I thought he said they would work on the 10 models. Let me search around a tad and see if I can find it..... ah, found it (see this thread: http://www.toyotatundraforum.com/vol...9-tundras.html)

And I have seen some initial improvement in mpg, but for some reason on my 07 5.7L, the mpg gain slowly erodes over time (see my post #5 in this thread: http://www.toyotatundraforum.com/vol...am-gasket.html).

Very interesting information. I can see how the computer would compensate for more air flow and richen up the mix resulting in more HP and less MPG. You would also think the computer would reset the timing as well. There are so many possibilities as to what the computer could be resetting when changing the air intake, exhaust out flow and so on.

I'm not sure I feel qualified to be messing with the factory setting when no one seems to be able to predict a consistent outcome.

With past vehicles I have owned, I have found the most reliable way to increase MPG is to use Premium fuel. In California that would be 91 octane. In my 1998 Chevy 1500 and 2000 Chevy 1500HD (it was a heavy halfton that they don't make anymore with a 6.0L gas motor) I improved gas mileage by 2 MPG by using premium over regular. I also tried a friends programer and it also improved gas mileage but I only used it for 2 tanks of fuel and then gave it back and never bought one.

The programer advanced the timing and I can't remember if it then required premium fuel or not.

You have to weigh the extra cost of premium fuel against the increased fuel mileage to determine if it is worth it.

My son and I did a science experment with a motorcycle 4 stroke engine when he was in the 6th grade and we determined that this particular engine would run longer on premium than on regular gas.

I'm going to run my new Tundra on regular for a year and then switch to premium for a year and compare. There are too many factors to get a fair comparison unless it it done for an extended period of time.

The new tires look good 2on2off.

Thanks for posting the pics of the TPMS sensors - I think that is the first time we have had some pics of them posted on this forum.
