The great thing about REVO is the flexibility it gives you. This means you are able to fine tune your settings for your particular mods.
To take proper advantage of this you really need to be logging with VAG-COM at the same time as adjusting the settings.
For example:
Buy a new intake - Log your Intake Air Mass before and after installation of the intake. If you are getting significantly more g/s with the new intake you will probably be able to up your boost a little. Once you up the boost log block 115 in VAG-COM and make sure your actual boost is able to meet your specified boost.
Buy a HPFP - Now you should be able to richen up your AFR a little. What does this mean? Well it means you can supply the fuel pump with more fuel which should in turn bring down your Exhaust Gas Temperatures (EGTs). This means you will be able to run a some more timing and this is when you will start making some nice power gains
Above is just a couple brief examples of what you can do. There are many many possibilities. This is the beauty of REVO, the SPS plus and VAG-COM.
