Not currently. There are issues with the the LS3 ecu that are different from all other C6 Corvette calibrations. Some of the tuning parameters that need changing may be beyond the capabilities of all the current hand held tuners. There are several software tuning packages that support the 08 LS3 ecu and several tuners that offer calibrations for that application.
Tuning the 08 LS3 is very different than the 05-07 LS2.
