    Diablo and PCM

    Posted by Jonathan Haas on Sep 2nd 2021

    The Diablo leaves a lot to be desired in the amount of tuning abilities it has. HPT has way more functionality vs Diablo who you have to have(and pay) a 3rd party tuner to make a custom tune. The Unlocked PCM worked like a champ though!!

    [RESPONSE FROM HHP: Thanks Jon for your review! Diablosport is a product that is designed to give you pre-loaded, tested, proven and safe and even emissions compliant tunes along with the option to make some minor changes yourself that should still allow you to stay safe plus they allow you to receive custom tuning from an actual tuner. You are comparing it to a software that is designed for only custom tuning, comes with no pre-loaded tunes at all, which means you still need a custom tuner to write you tunes unless you personally know how to tune these cars. Self-tuners are great for engine sales but the average vehicle owner should not be attempting to tune their own vehicle.]
