Tune with new cam

Hello.
I'm currently working on an engine for my 03 2500HD. 6 liter, 30 over, with flattops, 799 heads, and this cam:XFI RPM Camshaft GM Gen III/LS1/LS2/LS6 249-54-414-11
It says it requires a tune. Can the truck be driven to the tuner's for the tune? Or am I pulling the ECM and bringing it to him?

Just being careful--I'm a smallblock guy.

if its not very far im sure it will be fine. i wouldnt really be worried about hurting anything as long as the install is done correctly.

The guy is going to need the whole vehicle to be able to tune it properly. If that's an Auto you might need more convertor, see what happens. Should be able to start and drive.
