Shawn came in today with his 2007 Mustang GT Manual all the way from Massachusetts. His car came completely stock except for 93 Octane and C&L Performance 95mm Racer Intake Assembly. When we got him dialed in, his car ran a smooth and consistent 294/313 in
95-98 Degree Weather! Reference line is set at 13.0 reading POST-catalytic converter, which will bring his actual air fuels down to an optimum 12.7-12.9. SAE CORRECTION!!
