That's my main concern, I'm going to be utilizing a pretty aggressive cam. With that in mind I think that strictly MAF tuning the beast would be a PITA and probably not yield much for idle.
VE tuning is useless. Ive experimented on 25+ Grand Prixs of all different years with various OSIDs.

MAF tuning is not a PITA at ALL if you know what you are doing. You can go to a full time open loop tune to eliminate fuel trim issues with the cam. Again, if you know what you are doing, you can do a full open loop tune with a wideband in like an hour assuming there are no issues on just about any car. Idle will be rock solid at whatever you set it to no matter what.

Pwned.
