What should I do to protect my new engine?

Upgrading the injectors isn't a bad idea.

I have a 89' vert running on the stock turbo with a FMIC and 3" TB exhaust system.

I installed mustang 5.0 fuel injectors and after warm-up, the car runs wonderfully. Running 12lbs of boost on the stock turbo, I've never had any problem with boost creep or overboosting.

Max boost your looking at on the stock turbo is about 12-15lbs. Anymore than that and its more than likely that your going to break something....

This doesn't make any sense...
Stock V8 injectors are like 30 lbs. / second?
Even upgrade ones are only like 35 lbs. / second.
Stock FC turbo fuel injectors are 550 cc / minute, which is actually slightly higher than 50 lbs. / second.

30 lbs. / second = ~ 300 cc / minute
35 lbs. / second = ~ 350 cc / minute

Even stock FC non-turbo fuel injectors flow at 460 cc / minute, which is higher than stock Ford 5.0 fuel injectors.
