i have been looking at an ati procharger. the main thing about the system is that they use a fuel pressure regulater on the fuel. if i am right it about x4 or around that psi on fuel rail for every psi of boost. i have 19 lbs injecters on my 4.6l f150. is this a sound way to add more fuel for the boost it adds? i just don't want to buy and have to go back though there system and buy more to make it work right. any info on the system as far as install and the way it works will be helpfull in my research on this system. i have the info pack from ati on the charger and have called them on the phone but they ( being the person i talk to ) did not sound like she had that much tech experiance. but i could be wrong.
thank for any info.

The FMU will work fine. In fact just about all the kits for our trucks use one with their out of box kits. You can always install higher flow injectors with a tune for better performance in the future.

 

i was thinking about that as an upgrade for the supercharger. larger injecter, maf sensor, and have a chip custom tuned for them. i just i did not know if it will be a good idea or not.

More fuel is tuneable.....too little is a roadblock...

 

I don't like FMU's in general, Get bigger injectors, MAF, and a Chip from a reputable tuner. I've seen FMU's fail and its not pretty. Guess what happens when you loose fuel pressure under boost, nothing if you are lucky but usually piston damage. I'm a firm believer in doing things right the first time.
