FAST XFI camshaft limitations

with a fast xfi multi port fi system, can you program the computer to accept any camshaft size or is their a limitation of lift, duration or overlap which makes the system nort work well?

There are no limits with xfi.

awesome, thanks. First time I have messed with an xfi system

It's really pretty simple when you get messing with it.

do I need an expert tuner to get the motor running or do I venture through the programing myself?

There are some box programs that come with it.  I'm sure something is close enough to get you started.  It's pretty easy once you start the car after you set a few basic parameters.
