L92 PCM help...... which harness/controller?

[Samckitt]

So I have a 6.2L L92 heading my way soon and I am teetering on which harness/controller to go with. One option is have a new harness made & use the regular L92 PCM or 2010 Camaro PCM (evidently it will control the VVT). Doing this requires a dyno tune, but uses all factory GM stuff, so I could go anywhere to find out what is wrong if the check engine light comes on. New harness is near $1000, dyno tune around $500, cam & springs another $400 or so.

The other option I am debating is a MAST Motorsports harness/controller package. It is a complete stand alone harness, it has the connections for the ignition switch, Neutral / clutch switch, all fuses & relays in one little mountable box. But it doesn't use the mass air sensor & if the check engine light comes on I have to use their software to pull the codes. Controller/harness package is over $2200, software to pull codes is another $300, & debating going with their cam/springs package that they claim will make up to 550 hp at the flywheel. And their controller is pre tuned for it.
