JCON

They won't require a tune but remember on a dyno, your car is strapped down, on the street you're spinning wheels. With these suspension mods, you're properly placing more of the power you're making to the ground.

Correct - turn off the TCS and turn off the OD.

Just did a burn out infront of my place, just a couple seconds to get the wheels smoking. got two solid black rubber lines. was really worried that my rear was burnt up, that made me feel better about it. talk to a shop down the way about some custom x-pipe and i'm getting some suspension mods right now. hopefully I can install them in the next week or so thanks everyone
