Review on 📈 Edge Evolution CS2 85350 by Jason Mitts

Installed on a 2005 Silverado 2500HD with 140,000 miles. I bought my truck with 70,000 miles on it and it always felt underpowered for the 6.0. Last year I added a Specter Performance cold air intake and BBK Shorty Tuned ceramic manifolds with very little improvement. The Edge programmer finally brought my truck to life! Although I used it in Economy mode for better mileage, Performance mode provided a significant increase in performance! *I followed the recommendation to use 91 octane in performance mode.
