It may be worth it, if you don't mind giving up the selectable locking of the factory eLocker. The stock eLocker can't handle Whipple levels of horsepower and torque for very long, especially if you're doing a bunch of hard launches. The TrueTrac is much more capable of handling a Whipple than the stock eLocker. As long as you don't have an issue with being at the mercy of the TrueTrac's locking mechanism (which works very well in my experience) versus having a button to switch it on and off.
