Message: [QUOTE="maxxedout, post: 1421861, member: 15749"] I ran GH, briefly, but I usually run tunes from Midwest. The truck is balls-out fast at WOT, but low-to-mid range just isn't right. The truck fuels hard off the line, (not ridiculous, but definitely adequate), then something seems to pull it back right around 1,500-1,550 rpm. From there, it just feels flat/dead until 2,200-2,300, and then takes off like a bat out of hell. It honestly feels like I'm backing off the throttle until about +/- 2,250, and then it just goes. This is EXTREMELY annoying because from a roll, if I put the hammer down, it ends up in the middle of the dead spot. It doesn't matter if I'm at 50% throttle or 100% throttle, I have NOTHING until I'm well over 2K. The truck builds +/- 35 psi of boost at WOT, seems to hold good rail pressure, and there are no codes whatsoever. If I'm in a situation where the truck lugs, when I get to 1,550 or so, the truck starts to buck/jerk, like it fuels, then stops, then fuels, then stops. Once I get past about 1,600, the bucking is gone, but I have no power. If I didn't know any better, I'd say the turbo is sticking, but I can hear the vanes cycle at idle. [/QUOTE]
