I was smoked by a 4x4 Dodge deisel at a test and tune not long ago...couldn't believe what they are turning both HP and ET....well, she is off to a good start....I'm on hold now until the LSD's are done and installed...last time I launched hard with the DR's on, I heard a nice pop from the rearend, and luckily it was just a suspension pop and not a rear end....but, still worried about the slicks and hard launches...so, it will be next spring before we go back...
