So, I've been seeing a lot of threads/comments stating JB4 map 3 (+6psi) is destroying engines. The recommendation is to stick with map 2 (+4PSI) unless getting the logs tweaked or "tuned" I guess you would call it by @DaBears. This makes me wonder; is the additional 2 psi really that bad and if map 3 really does push the limits that much what benefit is there to a JB4 over a JB+. Both are additive maps rather than absolute targets and JB+ adds 4.5psi at max while JB4 adds 4psi on map 2.
I guess what I'm getting at here is for a guy like me who doesn't intend to do a bunch of mods or fool with E blends and the like, would there be any benefit to a JB4 over the JB+?
