Ask Unichip: Tuners For The Tundra 4.6 and 4.0?

Not all wrenching on the Toyota Tundra gets done with an actual wrench. The complex computer systems that manage the Tundra’s engine are a ripe source for unlocking extra horsepower. Somewhat conservatively-tuned from the factory, the Tundra has attracted attention from aftermarket chip manufacturers and programmers intent on squeezing every last drop of potential from the vehicle’s drivetrain. However, only Unichip offers a tuner for the Tundra.

The first part of our interview with Unichip

We were given the opportunity to interview Jack Friedman from Unichip, one of the authorities in ECU tuning. Unichip has been in business for more than 15 years, and during that time the company has maintained a strong presence supporting the many different engines offered in the Tundra. Jack provided us with an almost overwhelming amount of information concerning the ins and outs of Tundra tuning, and we’ll be sharing that info in a series of posts that should help Toyota Tundra owners get a better understanding of the ECU tuning process.

New Toyota Tundra 4.6L Engine

A few weeks ago, we acquired some photos and video of the 2010 Toyota Tundra work truck package that was shown at the San Diego auto show. At the time, it appeared that the 2010 Tundra would be more of the same. Rumors of a new Tundra 4.6L V8 surfaced a few months ago, but we determined that the 2011 Tundra would get the new engine (along with some other improvements) and our sources seemed to agree.

Evidently, Toyota has decided to step-up their time frame – the new 2010 Tundra will feature the new 4.6L V8. Based on the larger 5.7L, the new 4.6L is a short-stroke version of the big motor that generates 381hp. The new 4.6L will replace the nearly 10 year old 4.7L.

Here are the benefits of the new 4.6L Tundra motor:
