I used to have an SVT on SCT and now have forester xt using Cobb. Overall I will say the Access Ports are great little devices and there are a ton of parameters to monitor. Not sure if the focus will ha e it, but real-time flashing of ROMs are awesome: I can switch my tune from 93oct to e85 within a minute while fueling and easily switch back. You can also adjust timing and idle while the car is running.
The only complaint I have about the AP is I miss the logging of the SCT unit. For instance looking at the graph vs. the AP showing a spreadsheet of data. The real big thing though is that you are limited to the number of parameters you can log at one time. Just the other day I tried to add a only a few extra parameters to the default list and it gave me a memory warning. Hopefully you guys can address this in the future.
Overall these are great units and support seems to be good as well.
