Man I'm *almost* wishing I had snow's for this week. Va Beach hasn't gotten blasted with a snowstorm this heavy in a decade!

So I'm updating this because I wanted to talk about what happened with the dyno. I wanted to know if there was more area under the curve with the new impeller blade, and I really wanted to know what the deal was with fueling.
So, pre-cat bung holes/plugs were fitted for WBO2 sensors to monitor during the pull on the Dynojet 424xLC^2
All good right? Well, no, unfortunately. I was misunderstood. I thought that the 424xLC^2 could load up the rollers independently, (due to the F/R torque split) but they can't. Couldn't get a same speed lock at very low speed so we abandoned the dyno before one pull was made. Oh well.
We need this for the dyno:
Dynamometer Model 424Linx
My buddy (the shop owner) isn't just going to drop a fair amount of coin instantly because I want him too, (I asked though, haha) but he may get it in the future.
That leaves me with road testing. So I need to purchase a PLX DM-100 OBD II display unit and two PLX wideband O2 units
The goal is to get a read on the fueling, see if additional fueling is needed before any other change, see how close I am to running out of pump or injector, and then if I have fuel on the table to play with, to see if those cat converters could be made to "flow better". I think there are V.E. gains to be had there.
FWIW, apparently the pump is an E39 M5 unit, and the injectors are a Delphi product, still researching on what size they are exactly.
