When I had my car tuned, we were seeing some dips like that, so we added fuel to drop it down to 12.5 - 12.6 at wide open, added 2 degrees of timing and I ended up making 8whp more. I've seen a lot of the 370z and G37 tuned with UpRev and for some reason, they like extra fuel. 12.5 - 12.8 A/F seems to be making the most amount of horsepower / torque.
