    How does this not come with every stock Camaro..The second you step on the pedal , its instant reaction.. It almost scared me LOL The is one of the best mods I have ever seen and used...I have watched tons of videos and thought it cant be as great as everyone says...I WAS WRONG this unit is incredible , I only run it at 60% when im at 100% it wants to break loose HAHA , But I also have 525 HP as well, its a must , you need to have this PERIOD.

    Installed on 2018 Buick Regal Sportsback GS! Installation was quick and the results phenomenal! It’s a different car! Throttle response greatly improved! Highly recommended!
