Testing the HiRev 7500

Some of this is why I don't like the rule of thumb - "All in by 2800" curve that's been regurgitated for years. I've gotten clatter by advancing to total too quickly. Even without clatter, mid range pull wasn't as strong. For some cars it may be right, for others it may be way wrong. Kind of what I was talking about in my last video.. lol.. It's work, time, and money to chase tuning. It's not magic.
