Mine

J/k. There are some turbo ls4 guys making over 500whp, but I haven't seen any 1/4 mile times for them.

start saving for an upgraded trans lol.....i would think with bolt ons it should be ok but they are still weak so i have already started putting away a lil here and there for an upgraded trans when it goes out after warranty haha.

I'm not sure how they'd react to a catless DP. Federal law states that the burden of proof lies with the dealership to prove that the modification caused the part failure....but still....

Didn't the turbo MCSS guy run a 11.4? I'm sure there's a N/A that has hit 12.9 by now too.

I'm not worried about it. All I have to do is take off 4 bolts and put the old one back on.

Believe my car is the "World's Fastest LS4" both n/a and boosted:

n/a 13.0 @ 107 (slicks, HS 1.8 rockers, LS6 valve springs, Hogan DP, Magnaflow Exhaust, K&N intake, Diablo Tuner)

boosted 11.49 @ 117 (slicks, Cartuning Turbo Kit, HS 1.8 rockers, Patriot Gold Valve springs, HP Tuners)

Video's on You Tube.....
