Cobb has designed the AP to "marry" to the ECU it's used on. In order for sombody to lend you an AP, they'd have to "unmarry" it from their ECU first. The problem with that is my unmarrying it, they have to reload the stock map on their ECU. Plus, you need a custom tune for that intake. Cobb's canned maps only support the stock intake.
So you have to buy your own.
The $750 package I was referring to is what I believe most NorCal tuners are charging for a couple hourse of cutom tuning and an AP as a package. Install some more mods first though.
