I put a cam in my 4.8 yesterday and need a little help in the tuning dept. Im going to borrow a buddies wb02 this weekend but is there anything I can do to make this thing run until then? Wont idle and is crazy rich.
Im using efi live to tune.

 

Post up your tune and some more details (i.e. are the injectors, fuel pump, or MAF changed)...

 

How big is this 'big cam'.

If its a big cam for a 5.7/6.0, its going to be downright huge in that 4.8

 

Yup. Hard to ask for help without posting the tune, and more details.
