Motordyne 5/16 Plenum Spacer: Dyno Before and After
Went to go dyno the car after installing 5/16 Plenum Spacer (Finally)
Result: Gain of nearly 4hp and pretty much the same torque.
My best run was actually 249.24whp and 232.34tq
However, that run's graph got messed up, so I just posted 2nd best pull.
Torque gain is none/irrelevent because I have gotten more than 232tq even
before the Spacer install.
The Plenum Spacer leaned out my car more. My A/F at idle is 17+
The car feels like it's 'chocking' and 3rd gear doesn't pull as good as it used to.
5th gear pull has improved, and feels more torquey
Would getting HF Cats richen out my A/F?
I want to avoid ECU reflash if possible.
