its over 400hp stock, I had to put a AFE air intake on it because of the fender cutting. Then deleted the resonator portion of exhaust, because of the cantilever. So its pretty free flowing right now, and really throaty. It sounds great.
To bring everything back in check (speedo/shifts), its been efiLive'd
With the 4.88's it will throw you back in the seat.
But real hate is developing toward the "Traction Control" and "Stabilitrak". I dont think there is any permanent way to turn them off, aside from just pulling the fuse. That also kills the ABS, and lights the dash up like a Xmas tree. It kicks in the worst time, popping out into traffic from a stop. Its dumb, it idles the damn thing, and has nearly got me ass'ed. You can disable them on the dash, but they come back on once you get over 35mph of wheel speed.
Now driving it, I'm getting pretty confident in it. I tossed it into a turn on Monday over 60mph, and it hunkered and dug through the turn like a sportscar would. By the time I passed the apex and looking at the exit I was well into the gas accelerating. Was pretty good to feel that it didnt want to body roll, or wash the rearend out. Pretty amazing for how big it is.
As for jumping, I've really only jumped it once so far. might have had 6-8" (I'd be surprised if it was more) under the tires but carried it for what had to be about 50' jumping some traintracks. Potholes, asphalt patches, **** roads, intersections it pretty much rocks out on.
