I am trying to tune my profec b. If i turn it off i pull 15 psi with no problem. If i turn it on and i go over 16 to 20 psi it keeps bouncing off the high boost kinda like im hitting a rev limiter. it doesnt matter if i run 0 gain or 25 gain it will stiil do the samething. I tried turning the vac lines on the bc around but that made the bc not control at all. so i was thinking that i might be pulling timing? am i right?
