So I recently got a baseline dyno on my car to document exactly how much the 2.85 pulley swap/tune adds... (180 thermo, 95mm throttle body, CAI, axleback, 93 octane tune). Thought I would post up the results before and after so here is before.

Edit.... probably important to note it’s manual if you didn’t pick it up from the vid.
