Performance Chips

[KrackShotKarl]

Does anyone have experience with after market performance chips that claim to increase torque, HP AND MPG?

if you are talking about for a tundra...what exactly are you talking about? afaik they do not exist.

[KrackShotKarl]

Yes, for a Tundra, I have a 2010, and would like to get some better MPG out of it.

what your looking for does not exist for the tundra. if you want more HP get the trd supercharger.

The only thing that will improve your mileage is training your right foot!!
If you want to spend some money to do that, get a Scangauage or an Ultragauge. You can learn a lot about your driving style from them.

Ya, what he said.

someone should sticky a performance chip thread, these posts pop up pretty often.

then again, I doubt anyone would read it anyways.

Back in the day, you could substantially improve performance AND mileage by installing a holly atop a new intake manfold, adding a set of headers, dual exhaust and louder mufflers. Those days are gone. Modern engines (and skilled engineers) have already picked that low-hanging fruit.
Then there was a time you could make improvements to the electronics, sometimes by "cheating" the EPA with chips and other gizmos designed for (wink, wink) off-road use. Well, now-a-days, a whole passel of bright automotive engineers have already put that on your truck. If they didn't put 'em on the Tundra, we'd all be drivin Chevies.
Until I see some certified tests, my feeling is that what goes down is not the number of gallons you burn, but the size of your wallet. Likewise, the only performance enhancement is in the glibness of the salesman.
Chips? There just ain't no stinkin' chips.

The best I have done with some smart driving is 16.1mpg around town, and get consistent high 15s (hand calc'd and computer). I am guessing it will not get any better than that. The key is to time the green lights and go easy off the line. Your worst mileage is accelerating from 0 - 40mph. There is no need to hurry to the next red light. It makes no sense. My best highway is 18.5mpg. I have no complaints about the mileage.

it's too bad there isn't a 'chip' or a way to tune these engines. Toyota, unfortunately, has their hands tied when it comes to the tune of these engines. They tune them really rich (10-11 to 1 a/f ratio). They make them this rich for 2 reasons. 1. engine life. 2. to reduce NOX for the smog nazis.

When you make an engine run rich it runs cooler. Running cooler keeps NOX from forming and this reduces acid rain. But it makes hydrocarbons (raw unburnt fuel) to reduce these hydrocarbons Toyota uses probably the best OEM cats on the planet. The cats burn these hydrocarbons.

So what I'm telling you is that your cats are burning a lot of the fuel that you've paid for, not your engine. That fuel is literally blowing out your tailpipe, not pushing down the piston to turn the wheels.

There's about 15hp locked up in the a/f ratio and timing tune of our trucks, but Toyota locks down the code so that it's hard to break into the ECU. We're stuck with bad mpg and less power than the engine is capable of

Or tape an upside down thumbtack to the gas pedal and drive without shoes

Oh Actually I Got a Performance Chip "UNICHIP"
Unichip - 2010 Toyota Tundra tuning chip | car tuning
Buy the Q+ It costs around 600 Bucks..
and Add an Air Filter + Exhaust System and Reprogram your truck on a dyno.. u will see a big different..
But if you want to go for more but "MOTEC M4" and Add A lot of performance parts and then program the truck
You will gain a lot of torque HP and Great MPG

Are you running stock or taller aftermarket tires? I was getting 23 mpg after I put a new cai on and the jba dual exhaust muffler with the 4.10 gears and stock 31" tires. Then I lifted the truck put 37" tires on now get a whopping 11 mpg on the highway, 10 mpg in town and 7 mpg in 4wd. I plan on putting the 4.88 gears in to regain some of the lost hp and torque, but I dont expect to gain much mpg if any. You get more outta the correct gearing than anything else, but its certainly not cheap.

Really nothing is cheap when it comes to Toyota, everytime something breaks Toyota just hands you some ky and smiles.

Has any one tried TOYOTA TUNDRA GF Peformance Chip it sound ok who wants to be first ?????

You can buy a resistor from Radio Shack for $1.09.
