I do agree with that sentence of your post, lol.
470 hp is not "500+ wheel horsepower." You *did* provide a dyno on an old tune with 470, good for you, that sounds like pump gas numbers for a PS2 car. Either your claim of 500+ in your old video is crap, or you intentionally de-tuned to get the 470 number in your later video to give you a good before/after. Regardless, you seem to have a loose grasp of measurements, which is key to the claims you're making. Once someone who knows what they're doing, already has a well-sorted PS2 car pushing 500+ whp and decides to spend $$$ on throwing a barely different cam in to verify, maybe we'll listen. But you've provided some really shoddy data and your youtube history does *not* lend you credence.
Your responses are rude, and you can diss me all you like, but it doesn't change the lack of data supporting your narrative. I don't care if you're making money, it's the deceptiveness intended to get you viewers that matters, not the fact you've only managed to make $3 on the effort.
