If you increase your compression and don't change the motor's breathing habits then you won't see much gain. Raising the compression isn't just a quick fix, for the best results you should tinker with the timing, intake temp., and fuel injector mapping. The injector pulse time doesn't need to be changed, but the pressure should be increased on stock injectors, if you're looking at 11:1 then I recommend you use larger injectors.
Of course, you'd run into more issues as well but I won't get into all of that. Unless you feel like putting several hours into perfect tuning then don't go up by more than 1 point of compression.
