Stronger ignition = more complete combustion
Now you can run a little richer or simply decrease your timing a bit. I'd take it to a dyno with a wide band if I were you to make sure it's set right.

If you wanted to do a quick and easy check to see if adding fuel will help, go to the pim settings and add a couple % points. If your running the base map they should all be on 100%, bump them up to like 103% or maybe even 105% and see if that helps you out.
My guess is your getting better combustion and it can cause you to run a little leaner than you were before.
If that doesnt help then I might back off the timing a couple degrees but check the fuel first.
