I'm not sure what version I'm running now.. probably 17.
My iat was 129 today on a 90F day. I do believe if I remember correctly even with my open cover intake it was 137 ish last year.
Boost was still 24.5 and timing was at 7.5.
As to the other question, I'd much rather have the jb4 vs the jb+ that I can't log or have safety failsafe. Is it worth the extra power? I think so.. I would certainly like to see anyone's dyno .. but others with dragy noticed a good improvement.
