Truck runs great except when I put it at WOT. Truck will act as if I let off of gas and pressed it again. It doesn't not lurch as if it fell out of gear. It will do this repeatedly until I let off gas. I have fuel pressure, boost, tranny, and egt gauges. None of them fluctuate when this happens. I have sct programmer with extreme street tune, MBRP 4" straight pipe, s&b cold air intake. Ps: turbo does give a fluttering sound if boost gets to 20psi and I let off. Any help is much appreciated.
