what some don't understand. maybe even me.
but this is how i read it.
he live's in canada.they do not sell the SC.
so he bought 1 from a U.S. dealer, & had it installed.
than he sent his ECU to someone here in the us to get it(ECU) re-flashed.
and he had it(ECU) unit reinstalled.
thus the problem's, started.
there are so many if's here, it is to hard since no one here has access to the tundra, to try to figure it out fast.
it has to be done step by step.
if the ecu unit plugs are not snapped in,& you hear them clickin, that could be a problem, if...

It's the MAF sensor and/or the wiring to it - dead positive on this one. The only thing that would trigger those codes would be a MAF problem. The AIT sensor is part of the MAF sensor. I would carefully check the wiring and the connector to the sensor - check for stretched wiring at the split in the harness. Maybe someone pulled on the harness a little too hard. Also try cleaning the MAF sensor with some non-flammable brake cleaner (CRC brand in the red can). It's possible that it got contaminated from an over-oiled air filter, but I really do think it's mainly a problem with the wiring/connector to the MAF sensor.
Hope that helps!

Well I tried another MAF sensor today, and the truck sounded better. It was idling alot lower than before. But again once it got up to temp it started having the same problem. Took awhile for the codes to come in this time and there was one new code along with the system lean codes. There was a pending "random misfire detected". I'm dropping it at Toyota tonight so they can have a look at it.
You don't have any exhaust leaks do you... and exhaust leak at the header pipe connection to the cat pipe (right upstream of the O2 sensor) will cause lean/rich conditions... If the fuel trims reach a total of 30ish usually (long term plus short term fuel trim) it will trigger the CEL. Also have you done dummy checks to make sure the O2 sensor plugs are tight... I have seen that code from bad O2's, MAF issues and also the exhaust leaks like I said. Just checkin...

In order to experience the maximum performance available with the supercharger, please refer to the owners manual instructions to put the vehicle in VSC Off Mode. This will disable the traction control, vehicle skid control, and auto LSD features, which can reduce the maximum power and torque which the engine produces. Should a customer perceive a hesitation or driveability concern when in normal mode, this is likely caused by the VSC system attempting to reduce torque to manage wheel spin. Switching into VSC Off Mode can confirm this as well.
Instructions for enabling the VSC Off Mode are outlined below for '07 Model Year Tundras and '08 Model Year Tundras and Sequoias.
07MY -
1) Make sure vehicle is completely stopped.
2) Press and hold the VSC switch for 3 seconds. Vehicle enters VSC Off Mode. Auto LSD light goes out, VSC Off and Vehicle skid icon stay on).
08MY -
1) Make sure vehicle is completely stopped.
2) Press and Hold the VSC switch for more than 3 seconds. Vehicle enters Auto LSD Mode (Auto LSD light comes on)
3) Press and hold the VSC switch again for 3 seconds. Vehicle enters VSC Off Mode. Auto LSD light goes out, VSC Off and Vehicle skid icon stay on).
To return to Normal Mode, press VSC switch briefly from any mode.
from the powers that be.........
this pertains to the N/A and supercharged.........

The other simple solution might just be an air leak somewheres in the intake or SC plenum area. Maybe a gasket or hose seal blew out from the boost pressure causing a vacuum/air leak.

Still sitting at Toyota, waiting for service manager to get back on Monday to decide who's gonna pay (I assume). Been a month and 2 days since I took it there and I only drove it for two of those. They are of course saying the misfire codes are directly caused by the supercharger, probably so they can fall back on my lack of warranty.

Man, I hope you come out a winner on this one. At a typical labor rate of close to $100 per hour dealer shop time you're not going to be a happy camper with the bill

I wish it was only $100/hr, it's more like $150 here. I'm already not too happy that the truck has been sitting there this long.
