Looking for what to do to upgrade the fuel system in my 2013 denali. it is flex fuel so has the bigger pump(what size is the pump anyway lol)...

need to be able to support about 800hp. Really dont want to do a surge tank setup. What options do i have?

416
trickflow heads
SLP supercharger
10% overdrive balancer
other things lol

 

Unplug the FPCM have your tuner turn off the communication codes and drop in any pump and regulator you want hooked up to a relay and ignition on setup and have at it.
