I dont know who Wade is but i did have Mark helping me. To set the DYNO up for my motor, get it up and running, six cam swaps, four turbo swaps and injector swaps in two days made us very very tired. Even on an engine DYNO.
We tested six different cams in my motor within two days and yes you can tell between the cams on a DYNO. We also tested injectors and tips and could tell the difference on spool-up.
Now instock new billet sliders for the AAM 9.25" front diff. Its designed to wear forever yet take the shock load.

I got another 60k and still clicking miles on poor injectors using all kinds of oil we drained from empty oil containers. Anything from outboard oil, trans fluid, gear oil and motor oil.
