Jesse’s mean looking Z has spent tremendous amount of time at the beauty shop but this Z also packs some heat under the hood. After getting it back from the body shop Jesse brought it over to us to make sure his Z was “healthy” enough for some boost. This Z sports ATI’s Pro-Charger air-cooled centrifugal supercharger. It came to us with a UTEC piggyback EMS and we did a baseline pull to see where it baselined. Z is still running a stock longblock with larger injectors and Walbro pump.
You can see his blue baseline run was way too lean the way it came in. We yanked the UTEC out, performed a voodoo ritual & tune up (spark plugs, fluids, etc..), and lovingly tuned this Z. We ended up with a much safer tune and more power & torque throughout the entire powerband (red run).
