You could use a fuel pressure gage, check for proper fuel pressure then with key off, see if it holds for a bit. If pressure drops like a rock, you have a pressure leak. You can smell of your crankcase oil dipstick, if it smells like gas, it's over fueling or you don't change the oil and filter very often. Possible issues listed in text.
If these are high flow fuel injectors you need to install injectors with the stock flow rate!
Trying to beef it up a bit..and keep the high voltage coils and injectors..
I agree with F O R, if it isn't stock, it may cause problems.
