The throttle pots go out of balance
Why though? I've had mine reset before and a week later they needed doing again. I have had the throttle pots replaced too.
This is a common problem for a lot of people, I'm just curious as to how it happens. Is it wires corroding? Or vibrations knocking things out of position?
Don't use easimap, as the map isn't actually in the right place. Easimap can't see the correct adaptives on the cerb.
You need the dealer diagnostic software. This allows you first to balance the pots between left and right bank and then clear the adaptive values.
Adaptives are predictive map values to allow for the fact that all information the car sends you is old hat at the time you recieve it.
You can use the ECU to decide whether you got it right but not if you'll get it right. Adaptives are the result of this argument and therefore form a better guess for next time.
P.S. I bet there will be someone who can do this for you at your local meet.

Someone called me the Cerbera Womble the other day, don't know what they meant but perhaps I need to change my ID? 
The throttle pots used on the Cerbs are cheap cr4p, I believe Joospeed has access to better ones, but they tend to die or more likely become 'noisy', hence the mapping is trying to hunt for a correct setting, ergo rough running. They can be set with the aid of the software but you will also need a flow meter (a Weber part from Demon Tweeks) to ensure you balance up the banks correctly. If you are unsure, don't do it, talk to the specialists. If you want to ask about any of this best email me off-line
