ZL1 FI Interchiller
Hey guys, this is probably a dumb question but I'm not very mechanically inclined. Does anyone here know if the FI Interchiller system for the ZL1 requires a tune in order to be installed? I've had my ZL1 for about a month now and have noticed some heatsoaking and wanted a fix for it without voiding my warranty. My local chevy dealer has given me the go ahead for stuff that doesn't touch the PCM like a rotofab and exhaust and stuff. Thanks!
