Thats what happens when you place a sticker on a car during a dyno run, then you take it off. Horsepower instantly increases, and as soon as you put it on, then goes back to normal when you take it off.
Ran into a lot of funky issues. Started with a base whipple tune that had all kinds of funny things changed around. Also, these are the total dyno pulls that have ever been done on my car on that dyno, so they weren't all in one day or anything.
