howdy, I'm using the tru boost on my 2jz mkiii swap with stock computer and finally got it dialed into 13psi or so without boost cut, but after a few hard pulls i check my "high boost" and it has picked up over 19psi. ive been monitoring the gauge under hard pulls and havent seen it flicker over 14psi so the only thing i could think of is surging after i ease off the throttle? anyone else hear of this? research has not helped me any.
