Ok I just picked up a teg and its got a vafc in it wtih h/i/e, I checked settings and its at +0 all the way across the board. Its totally stock fuel system is this safe, im hella scared to dump it to redline knowing that detonation could occur.

 

nothing will happen to make it detonate with I/H/E with settings at zero. i would suggest leaving the vtec x-over at the stock point, til you get more stuff and tune it.
