Re: injector upgrade???????

I doubt it: unless you have some serious head work done she won't need the extra fual IMO.
First i'd look at extractors, then maybe some headwork/cam, or an EF head even.

My 2c anyway :)

my car is now starting to lean out up high, due to lack of fuel, but has full exhaust and wade cam. a higher pressure fuel reg will push more fuel through the injectors and solve it.

even jmm says that fords fuel system is good for 170+rwkw with just higher fuel pressure.
