Ok, after some painful research, crunching numbers, yadda yadda...
I thought id share this with everyone thats trying to install it, because the instructions are pretty generic.

Hypertech instructions: DOWNLOAD

1. Fill her up!
2. disconnect the negative battery cable
*This will reset your ECU and give you accurate reading and gives the truck some time to learn your habits and calculate mileage.
3. Follow the stupid Hypertech instructions.
*Steps 3, 4 & 5b can be ignored - (Negative cable disconnected, remember)
*If it pleases you, follow the instructions
4. Install the cables
*Run the USB cable down towards the kick panel, itll make like easier
5. Put everything back together, minus the kick panel.
6. Install the USB cable
*You might need a laptop with Windows XP
*If you dont, good luck
7. Plug in USB cable, wait 1 minute for it to install
8. Run the Speedo Program

********PROGRAMMING*********
1. You CANNOT program your gears & tires
*JUST DO THE TIRES, MUCH EASIER!
2. Choose Tundra
3a. 33's, 35's, 37's
Enter 32 for Tire Size (OR look on the doorside panel because tire sizes are different)
*275/65r18 are equivalent to 32's (diameter)
*Enter in your NEW tire size, mine was 35
3b. for those that have 285's 325's etc....
*enter 275/65r18 for original (OR look on the doorside panel because tire sizes are different)
*enter your new tire
4. Your battery is still off, your truck does not need to be on
*CLICK PROGRAM
5. Close Program
6. Disconnect USB cable
7. Replace kick panel
8. Replace battery ground

*********TEST DRIVE**********
Download a SPEEDOMETER app on your smart phone.

Get on freeway, and try not to look at your monitor but feel a difference in acceleration, i DID!

My Tundra, 4 in lift, 35 Toyo MT, and 4.88 gears....
Nice smooth acceleration and good shift points!
Ill report back on MPG, currently 9.5/10mpg city/hwy

When youre cruising at 70mph (odometer) you should be at 2000 rpms.

If youre off by 5mph, like everyone else was, read the instructions again.


Good Luck!
