Default ZL-1 Spark Plug Gap

I have a spec zl1 engine, just installed TI ignition, and was curious on how far I could go with the gap on the plugs. I started at the factoy spec of .035". After I ran that for about 2 weeks, I pulled the plugs and found they were nice and brown color, but not enough pep in the acceleration. I opened them up to .044", and the engine now winds up quick and lots of power. Am I going in the right direction with this?
