Tuning

Well a little more information...
I still have the stock fuel pump, which I may be rewiring with 10 guage wire (vfaq said it was a good idea)
I don't have an SAFC, I'm in the process of getting one, so I've been using just the maf traslator to change fuel settings,
the maf has 4 adjustible settings, Idle, midrange, high range, and WOT,
I have it set right now so that it is -8% idle, -4% at mid, +2-4% high, and +6% at WOT (the percentages is +/- the stock fuel delivery (all based on airflow)

I am getiing a bit of boost creep, i'll star creeping from 15lbs to about 18+lbs at about 5krpm so that may also be why I am knocking,
I'm still using 92 pump gas (somtimes i come across 91 non-oxygenated, but i don't know if that would help))
so somtime in the near futur i'll be proting my O2 housing to try to get rid of this creep,

if that gives you a bit more info...
I still run into that fuel cutoff wall at 6-6.5k rpm which really sucks,
so if you have any recomendations or idea, or if you still need more info, let me know

Yeah, Your probably running out of fuel if you arent even rewired. I would go do that ASAP. It doesnt take too long and its a pretty easy thing to do if you have a strippers and connectors. You need 10gauge, the relay, a fuse thing, and some 12-14gauge for the ground. Or at least thats what ive done. It doesnt hurt to go buy a walbro too and rewire that.

18psi= too much boost. I have logged a few cars at 15psi that were knocking pretty good. Do you have a big floor mat on the floor? Try removing it and see if you can get 100% throttle then. If not, I would adjust the cable a bit before checking hte sensors. Adjust it with your logger on so you can get it set.

your out of fuel
You have 2 options.
1) buy a fuel pump.
2) buy pistons.
Its your call.
