Update:
Dyno'd yesterday and had some good and bad news.
Bad news, the #1 injector seal isn't holding, and is spraying fuel out of the seal when boost hits.
Good news, we did around 20 pulls on the dyno. Made 759 whp @ 29psi with E70. I have the graph for the 753whp pull, gotta get the other one. But the car still has more in it. We should be able to hit 800whp around 32-33psi. So I just need to fix the seal and see if that fixes it.

Very very nice , you guyd did an outstanding job! The power is right there for the boost you running.
You actually made more power than a gte will on the same mods.
E70 is enough to crack 900whp, so you are good to go.
Again congrats! !!

Thanks man. I think I may be lacking in fuel pump pressure. I have dual walbro 255's, and my tuner was saying that they will start bleeding off pressure around 72psi. Not sure of that though, I thought these pumps were enough for up to 900. But yeah, I want to hit 800whp. Gonna fix the injector seal leak and should be good to try again.

So after much research, I have decided to order (2) Walbro 485's, a 160amp Alternator, and 4 gauge alternator wire. I will have pics when I install the new stuff. The Walbros in the car right now are hardwired so I will check the wiring to make sure it is a proper gauge from the battery to the relay.
