You laugh, but there are actually people disconnecting vacuum lines and messing with timing to generate artificial cam lope...
How to make artificial cam lope
I had a customer who leased a V6 Camaro from me. Three years later, he comes to return the lease and it sounds like it has a radical cam in it. I ask about it and nope, he installed a thing that purposefully made it run like crap so it would sound like it was cammed. He traded it for a new 4cyl turbo Camaro.
