FedEx just delivered my sct tuner but the cai will not be in till next week.It is part#3000. I know steeda downloaded a custom tune for the cai,my curiosity question is there is also a 93 octane tune installed in the tuner. Could it be used for the boss engine or is it only for the gt's?. Sat. night,steeda is closed if nobody knows,I will call them monday morning. They did ask for my pcm number,that is all I know.
