Programmable Tuner for Chevy Tahoe?

[TimothyJones]

I want to do a performance improvement.
Whats a good tuner programmer for a 2010 Tahoe? Looking to improve throttle response delay,shift points and stop that pesky 8 to 4 cylinder deactivation. Thanks in advance.

Ask Adam Blevins. Tuning cars is his day job.

Look into black bear performance or diablew. They both do a lot with custom tunes on GM vehicles. Just google either one and you'll find plenty of information.
