Anything affecting boost, includig boost map. or wastegate duty cycle changes are prohibited. The later is what Nate is tweeking to avoid creap I believe. I don't beleive you can avoid creep with timing and fuel only which is what you are legally limited to.

Um, isn't that what I said?
"Engine management is legal, as long as you don't change the boost map."
I never mentioned whether or not that means you'll be able to fight boost creep w/ EM. If that requires changing the boost, then you won't be able to fight boost creep with EM changes.
'Course, as we've discussed before, boost creep is a mechanical problem! If the WG duty cycle is at 100%, and the car is still building boost no amount of EM changes are going to make a difference. The stock ECU can already open the WG all the way, so how is a remap going to completely solve the issue? Perhaps some tweaking might help in some cases, but at the root of the problem is the physical design of the turbo.
So, if you plan to race in ESP, without a cat, chances are you will boost creep. Leave a cat in, or come on over to SM where you can port the wastegate, and run a better boost map.
