Chipping? Of course it's rendering the warranty void! Racechip adds ~20% torque, meaning that also the ZF8HP75 is overstressed 20% above max design specification. You would need a ZF8HP90 like used for a Bentley.
It's only a matter of time before you'll demolish the drive train. When you would go extensive stretches flat-out: mechanical engine failure because of stress and heat build up by the power is to be expected. When you accelerate full throttle in lowest 2 gears (short bursts), you'll ruin the transmission and potentially the drive shafts and diffs because of the torque.
Proof: they upped the power of the competition (a bit), but didn't touch the torque! Why do you think?
