Installed this baby at lunch today. So far I am impressed with it. I downloaded the update with data logging (have not used it yet but its there now). I was leaning towards the Edge but I talked to a guy on a job site that had the Superchips on his 05 F150 5.4 and he loved it. I picked this one up locally for around $450. So far I am impressed with the wake up call it sent out to the FX4.
