I never had my truck catch fire, ive read about it on other forums though, and it sounds scary.

You got it down. Well if the pump is bad enough, it will tell you by throwing the dreaded 1211 code(alot of people with chips throw this code), or in some cases the SES light will flicker when holding the pedal down. Another way is to check it with auto enginuity, ford scan tool, etc, a good scan tool that can read the sensor. This is qouted from swamps...
"If you can maintain 2800+ psi of ICP, then any injector 250cc's and under will perform exceptionally well.
If you can maintain 2400psi then that's not bad, not great either.
2200psi is mediocre, and full performance from any injector will not be achieved with that HPOP, though power WILL go up with nearly any injector, driveability (excessive smoke) might be an issue.
If you cannot maintain 1900psi, you might seriously consider an aftermarket dual HPOP system, or our Gen3 HPOP. Nearly any larger injector is going to make the truck feel sluggish, and smoke excessively."
Basically states whats the good the bad and the ugly all inone shot.

I noticed a change in mileage it went up maybe .5mpg. I went because i was planning on a tad bit bigger injectors in the future, and i needed to have a better hpos. Instead of going for duals I got this pump cheap and just installed it. Theoritically it would make since for the mpg to go up since it is injecting the fuel at a higher PSI.
