Edge Products Insight CTS3 Series Tuner
$427.95
Q:Can this actually tune or only read and delete codes?
Spooner
A:BEST ANSWERHi Stacy, I'm pleased to assist you. The Edge product Insight CTS3 Series Tuner 84130-3 can only read and delete codes, it cannot tune. It is a monitor and diagnostic tool that allows you to view and record vehicle data, such as engine RPM, boost pressure, and coolant temperature. It can also be used to clear diagnostic trouble codes (DTCs). We currently do not have a product that can be upgraded to a tuning device. Contact us again if you require any other vehicle parts. Have a nice day! Show less
