start from scratch?

[broken_joke]

i am currently trying to get a tune going again after a repair of a broken piston, replacement of heavily damaged headers, and a new cam. for the experienced tuner's would this be an occasion to start from scratch or tweak on what i have already got?
thanks

Thats a good question. I have been trying to decide that as well. I have a pretty good tune on my H/C/I set up right now. I have a 347 going in this summer and am trying to figure out if i should just change the relevant info or to start from scratch.

i just redid a tune on the za0 for kicks and it kinda seemed to cure some of my issues. so it might not be bad to start from scratch?
