Hi guys, I came here over from the tundra forums. I have a 2012 doublecab toyota tundra with a 1GR-FE the updated DOHC 270 HP model. I am looking to make more power or even supercharge it within the next year and a half. Transmission has an upgraded valvebody and has been rebuilt at 133K currently at 145K. Just did the valve body upgrade around 139K. I love toyotas and this truck is important to me I do alot of the work myself to learn things and when I fail which I have once I turn to professionals. Forums like this one are the only reason I have gotten so far with my build and I am extremely thankful for that. I know you guys ran the engine for a while and I figure you have much more info on this than anyone in the tundra forums.
For a supercharger take a look at Magnussen. They made the kit for TRD, and when TRD stopped they began offering it with their own name. It provides about a 30% power increase (and the mpg will drop accordingly). I love mine.
Some people find the Pedal Commander makes them happy (it costs $300, and is really just an amplifier so it opens the throttle faster than stock, so your own ankle can do the same, but those who own them say they are very happy with its "performance" feeling).
Bone stock 4.6's do 270-290 at the wheels usually. The SC has bit more potential, again $$$$ for the wrong engine in the wrong truck.
I would trade any form of boosted 1GR for a stock 3UR swap with zero hesitation. I'm already making more power but the 5.7 has a very nice character for such a beast.
