Could I safely stack a Bully Dog rapid power and a PPE hot +2?

I know the VA box stacks well but I have heard of problems with turbos, head gaskets, and high EGT's. I want a switchable box that can stack welll with my 300hp tune for those time you just need a little more power.

Hey i'am out of G.R. if you'd ever want to meet and talk Max stuff let me know Wayne
