supporting mods just to run sts kit?
what supporting mods do i need to do to my ls1 to run an sts kit on my car to make saftly 450-500hp at the wheels.
here is what i have...
walbro 255 fuel pump
fuel pump hot wire kit
aeromotive afpr
26lb injectors
ls6 intake
longtubes

You'll "need" some new valve springs, at lest 42lbs injectors, although I went 60lbs just for ***** and giggles. You need the fuel pump, a Wideband is suggested and obviously a boost gauge. Most important...get that nogga tuned.
