346->408 tuning

I tuned my previous setup with the stock 346 and MS3 and felt that I had a good handle on the tuning. My new setup with be a 408 with all the bells and whistles. I will be upgrading to 42# injectors and I think I can figure that out but what about just changing from a 346 to 408 displacement wise? What hard set parameters need to change?

Anyone that has a 408 and could send the HPtuner file my way just to get me going I would really appreciate it. Really just looking for base VE, timing, and RAF numbers!

Thanks All.

this takes you through all the basics, then just do ve/pe/maf on top of it and you're good to go.
