I wouldn't say that it is harder to tune, but my experience with running larger than required injectors is that you will actually kill some power down low. Stuff that does not show-up on a normal dyno pull, but is evident on a time slip. The 30's should be plenty big for your combination.

There is a guy on another site, that goes by the name Injuneer, that has an awesome formula for figuring the minimum injector size for a given FLYwheel horsepwer. All you have to do is take your estimated FLYwheel horsepower and multiply it by 0.07.
This calculation takes into consideration an 85% injector duty cycle and a 0.476# per hour / per horsepower BSFC. (Brake Specific Fuel Consumption)
So, for example, if you take the estimated 500 hp and multiply it by the 0.07 number, you get a minimum injector size of 35#'s.
Hopeb this helps.
