So my family already owns the HP tuners equipment from other projects for LS swapped muscle cars, ZZP tune utilities this equipment and is by far more affordable this way then the BNR tune. The BNR tune claims 40+ gains on Hp/Trq and a lot of people testify to this. Can anyone give any opinions or testimonial on the ZZP tune? I have a SRI intake but also plan on a down pipe, injectors, and PCV valve fix.
