All the dyno results are posted here:

I've expanded upon how the lower plenum was machined. And recently, I expanded upon the machining process even more.

The lower plenum modification makes very good gains. And it made quite a bit more TQ than the spacer ever made.

The best part is you can combine the the lower plenum modification with a spacer for even more gains.
