I've had the plugin in my car for a few years, since they first came out. It was because my tuner uses them, they moved on from Autronic.
I'd recommend one. Only change needed is the wiring for Map sensor. Runs the car well.
As stated, a late model Link will also do a great job and cheaper. Mine was pricey, considering I don't use much of its features.
If I change my injectors, a retune will be needed so I'll use that as an excuse to upgrade the firmware which is better now then when it came out.
