With the ability to disable Auto Stop & DFM, on top of Throttle Sensitivity adjustment, without writing to the ECM, I'd prefer this over the Range OBD devices. You just get more for your money with the Pulsar LT. The install is fairly simple and you can make adjustments very easily from your cruise control switches on the steering wheel.
Here's a vid on the Throttle Sensitivity adjustment.
