Increasing ve adds fuel. How are you determining that you're running lean? Most likely you won't scale the whole ve table, just certain parts of it. You could also use the ifr table if you want to scale the whole thing. Multiplying by less than 1 will richen it up because the computer would think that there is smaller injectors so it increases the pulsewidth, which makes you run richer.

Thanks. I had my car on a dyno with a wideband and saw I was running lean.
