Update: Posi is in, loving that! However, still not a lot of traction, but much better.
Also, strapped the truck down to the dyno:

Also, the baby turbo likes it's bottle to. Added a dry shot. Started with 35 jet, then 50, now at 75jet and 15psi boost. I re-drilled my T-Stat, truck truns around 175 now. Also AIT only raise about 5 degree nows on a 3rd gear pull when spraying.

What did u do with wiring at the tank? i plan on putting a big external, and a hot wire kit. Just use the stock power wire to "trigger" the relay? and leave the rest of the wires hanging?

I use the stock power wire to trigger a relay also. The pumps have a 8 gauge feed power wire direct from battery. The top of pump housing is drilled for the wire and 8an fuel line connection. Inside the housing is Y'ed to the two walbro's.

Lol, well damnit it was sitting in my gargage and it was calling my name everytime I walked by it. Besides, I only spray it when i'm having a boring or shitty day lol. Also makes my Borla exhaust a little extra throaty when it hits!
