Do you have a chip burned for your computer??? I would look into that if your worried about it running rich. Best money youll ever spend in my opinion especially with bigger injectors and mass air stuff.

No chip...not gonna do it till after I build the engine.

I bumped the pressure upand it started up great this morning. So why does it make a difference?

you shouldnt have to turn down your pressure... they dont constantly putout 24lbs only when you SLAM the gas, the computer will know when the engine needs the added fuel. just set it back up
This is why it makes a difference. If you have a mass air calibrated to the 24# injectors, the computer dosent even know it has bigger injectors.

Because it takes a certain amount of fuel and pressure to fire a cold engine. Just b/c you have 24's now, as redpony stated above, the computor is still able to compensate for it.
