my friend tinted the truck today
i cut out the stock map, and installed a 3 bar, upgraded the truck ECU and OS to 3 bar speed density.
cut out the stock maf, evap, and egr for now, relocated the IAT from the maf wiring into the intake behind the throttle body where the Evap solenoid used to be!

i think im also gunna pull out the clutch fan and install Efans to clear up some room in the front for the intercooler piping and couplers that will come

yes, you just have to upgrade to a 3 bar operating system and make sure the map values are changed with EFI live/HP tuners. I run the same map sensor with a 99 fbody computer.

yes, i am running twin 400s, seems like i need a bigger relay for them i was just looking up a thing that says they draw nearly 20 amps a piece goddamn, they are beats but my 40amp relay is getting hot, so im gunna get a bigger one for them.

first i thought the wires were too small, rand all new wires and larger connectors, moved grounds, replaced the fuel filter, etc etc, now its still just the relay getting hot lol

wasted all day ******* with it, but oh well.

well today i messed around quite a bit.

had to drop the tank 2 times, chasing what i thought might be wiring issues, but turns out the fuel pumps draw so much they were just making my relay hot, 30A continuous and 40amp peak...

oh well least i have crazy wiring to the tank, brand new fuel filter, the old one was clogged up bad, and i ordered some 70 amp relays...

after doing some reading up these things draw like 16-18 amps at 5bar, 13.5v... crazy!

anyway we drained the tank, wich took forever because the fuel filter was pretty clogged, we took around 25g out of the tank, took about an hour.

once we got the tank out i used a nice Y fitting and modded the basket to hold these big boy 400s.
