Yep, sure can. Since the CMD doesn't skew values going into the ECU it'll perform fine with the PA reflash. Unless the Ignition module comes out soon I'll be going that route most likely. Something about 300whp without timing control makes me nervous, I may be offbase there, but... Unfortunately there seems to be a lot of people having issues with the PA reflash and using cruise control. A thread at the other GC site has at least 5-10 people complaining about limp mode and random loss of power when cruising, without cruise control as well.
