True. I just assumed that he had one

I usually do a regulator before anything else. Like he said - get an adjustable regulator and while you are at it, maybe an aftermarket fuel pump, as the stock pumps can barely keep up with the 19lb injectors
Even then, consider a chip to fine tune your setup. A few things about chips:
1 - Dont buy one of the out of the box, one fits all chips. They are guessing just like we are when we drop in a massair and injectors. Only get a custom chip tuned by a good shop while you are on the dyno.
2 - The downside is if you make even one little change to your engine, the chip is probably not optimal any longer and more dyno time is in order.
3 - Man this hobby is expensive!
