Default upgrading cam on 454 mag crossram efi

I have a set of 454 285hp crossram efi mags and i was curious if this computer is tuneable or would i have to go to a stand alone for any serious upgrades?

I've been thinking about doing a slight cam upgrade on it, but down the road i would like to pump out a. Bit more.

I wouldnt think a slight cam upgrade would do anything, bit if i can get another 200rpms out of it im curious if i would be fighting a srock limite, which leads me back to the sdjustability question.

The short answer is yes the MEFI controllers are tune-able. You would need to install a wide-band O2 sensor to do so.
