Default Boost creep w/ Cobb??

For the guys that are stage 2 93 octane...

Does the Cobb map eliminate the fuel cut defencer? From what I've seen the FCD stock kicks on if it reads more than 17 lbs for 2 seconds? with a boost increase like the Cobb w/ a turboback will this kick the stock FCD? If so, is there any way to stop it from doing this? I plan on odering a Cobb and Walbro fuel pump just to be safe, but I was just curious if any of you guys have experienced hitting fuel cut since the installation.

It's not boost creep if it's a tuning issue. If you don't have boost creep now you won't have boost creep with the cobb maps. Boost creep is a mechanical problem.
