You went rich due to catalyst / exhaust component overtemperature.
You will get the best power if you can do it with the coolest exhaust possible.
High loads and high rpm's can get into rich temperature protection.

He had the Typhoon intake installed, but his was done in third gear as well.

They should be done in 3rd gear

Either way, that's an ugly dyno. Spikes and valleys everywhere (I assume smoothing was minimum).
Kinda wondering if it wasn't strapped down tight enough. That'd explain a lot of it away.

Aftermarket will do nothing for the rich operation. That is all in the cal as exhaust temperature protection. You need a cal to 'fix' that...not that it is broken, your exhaust temps may be at a point of needing cooling...
