Review on 🖥️ ACCEL 49505 SuperTuner - Advanced Handheld Computer Programmer by Gregory Castellanos

Purchased for 2005 tahoe z71. Even though Accel's own website doesn't list my vehicle as compatible with the Supertuner, it does support it. I downloaded the updates to my laptop and downloaded them to the PDA. 25 minutes. Voices? Very simple/clear. Melody? Performance octane rating 91. Results achieved? Beautiful, not exciting, but nice. $268 was pretty well spent. (Results are not as impressive as my 2017 Silverado 5.3 / Diablo Predator2 Platinum. Diablo modified this truck😊)
