Its got the same fuel system as the other trucks. It didn't take much for me to max out my injectors. I'd say that by 340 rwhp they are done. I believe they are about 24.5 pound injectors. Fuel pump and rails etc will handle more, but probably not much over 450 without some upgrades.

Anyone know how much fuel pressure they run and what size injectors. I am thinking I at least need 28# injectors, does the fuel pressure drop on these like the f-body.

58(+/-2) psi fuel rail pressure (at 0" vacuum), with a vacuum referenced regulator (gives less fuel pressure as vacuum increases)
