My friend has a 2011 Tundra 5.7L with a supercharger, cutbacks, headers, and intake modifications. The engine is running great but it doesn't seem to be communicating with the transmission correctly.

I'm obviously new to this but I'd really appreciate some help getting pointed in the right direction.

The transmission isn't shifting on time. For example, if you put the throttle to 100% it will accelerate smoothly through first but redline for a second and the jerkily shift into second.

Any suggestions? New Chip? Where to buy?

Thanks
