    Do these programmers really help?

    I just bought a 2003 suburban z71 pimped out might i say, but the previous owner, gave me this thing its supsta optimize your performance, will it help if i just use reg 87 octane fuel instead of 93 octane?


    its kinda pointless i think on a huge SUV, but if it was for a sports car that would be cool
