I think the only difference is the spray pattern. The ford racing ones are good and have been used by others with no problems. Id go with 30lb injectors however since its about the most motronic can handle.

A "copied" chip? Nice.
(please note sarcasm)

I'd suggest a megasquirt, frankly. It's THE best thing you can do for this kind've stuff. It's relatively cheap to implement, it's OpenSource (so you can copy to your hearts content ), and it's really quite flexible. Tuning IS time consuming, but there are so many tunes out there, you'll probably find an existing one that is "very close".

I'm not sure if it can handle 36lb. I *think* somebody was running 42lbs on the stock computer but later threw it out for MS.

As far as options go for tuning, you just listed em

You got a copy of the TCD chip I developed for TCD that he wanted to pay me peanuts for? That chip only has timing mods. You need a custom tuned chip to handle the fuel also.
