Superchips Bluefin sounds like it would be ideal for you. It's a handset that you use to upload a map to your ecu via the diagnostics port. The map is already on the handset and all you do is plug it in and it uploads it to the car. If you want to take the map off again then just plug it back in. It's really simple and easy to use. The superchips remap is decent and you will notice the difference straight away, it's not as aggressive as remaps offered by Revo or APR but obviously it means its easier on the drivetrain and engine etc. Revo and APR are the maps which produce the most power and there is nothing between the two, but with APR you get a system where you can change maps via the cruise control stalk. Revo have a device which allows you to change parameters like fuelling and timing but it does have optimal settings so I'm not sure how much use it is on the road unless your tracking it. All maps claim over 300hp.
