Little late seeing this but for any future similar situation, as long as the cam phasers are timed correctly & physically locked in the normal full advance position (where they are locked by design when no engine oil pressure is present), then engine can be started & ran normally. The tune will freak out & set codes but will not stop engine from running.....much the same way if the VCT solenoids were unplugged & engine ran......how some test the VCT solenoids for sticking.....
This way you can drive the car to the tuner's shop to get tuned.....but there's nothing wrong w\ being safer about it & tow it there instead.
The big issue w\ locked cams in these 3V's is when someone is mechanically phasing the cams (physically setting the ICL to a position that does not coincide w\ the normal locked cam phaser full advance position) & doesn't make sure that their setting doesn't cause piston to valve interference prior to startup.........
Either way is fine so you do you.
