Nice numbers, but that thing needs fuel above 4K unless something was wrong with the dyno. That thing is pretty dang lean up top.

I agree as well. That A:F ratio is INSANE. Your car should be at ~13.0:1 or LOWER at WOT. I would have your tuner look at that again.

yeah the first pull was better, it was alot lower on the scale, I personally believe the pump was going out. Now I am having issues with the pump just shutting off.. but i just got my racetronix kit yesterday. :D

no there were no dyno issues, and i am betting to have 365-390 at the wheels with all the fuel there...

The Racetronix kit is the shit. Amazing setup. Did you make sure to get the harness with the pump amp? If you haven't done it before, it's much easier if you cut an access panel in the trunk. Look it up, it saved me 5+ hours of tear down and probably another 5 hours of reassembly.

yeah i got the new wiring harness, with the connectors for a boost a pump or whatever. i definitely want to do the pump thru the trap door. did you have any corrosion issues or anything with where you cut the metal? did you paint it or anything? just trying not to make a simple mistake... as it sits, the beast is sitting in my garage with a full tank. not exactly something i want to remove from the car. not to mention the rest of the shit included...
