any help is appreciated, running 550 injectors w/ afc hack rev hard stage 2, idles at like 7-8 hundred... but will shake than calm down, than shake and rattle again

 

you probably have to lean it down a bit more on the v-afc. and set the fuel pressure regulator to stock pressure, thats alot of fuel pouring into the motor on idle.
If you already did that then probably your spark plugs are starting to get fouled out, you might want t o change them.
hope that helps.

 

when my motor was untuned it shook like a bitch. It was running mad rich at first.
