Well I haven't tried, nor am I gonna try either of them. But they are both hogwash.
First, I wouldn't trust any item on ebay that starts out with a "Notice to eBay" referencing the auction. The seller in the first item has private feedback. I don't trust any seller that keeps his feedback private. Especially when you can tell that he has received negative feedbacks.
Second, they are both IAT sensor mods and no one has any dyno proven results of this mod on an N-Body. It will NOT give you the advertised HP gains they are stating. The first auction is just in a flashy package. I love how the pic at the bottom has $149.95 on the box so you think your getting a great deal.
Third, someone around here can tell you how to do this mod if you wish for a few cents with resistors from Radio Shack.
