OMGHi2U Boost creep with catless DP and cobb OTS stage 2

I haz question... Have any of you experienced boost creep (and/or spike) with such a set up? I just ordered an AP, Invidia V2 and HKS catback for my 05 WRX. I only hear about boost creep for the 2.5L WRX/STI's on the forums but I've spoken with some vendors who are adamant about only using catted DP's with cobb OTS maps even for the 2.0L models.

Should I be worried? I've heard of fixes like porting the wastegate, using a 'restricting pill' to create back-pressure, or running cobb's LWG map... which would be most effective?

I might also get a catless uppipe... does this change anything? (boost creep-wise not hp/spool rpm-wise )
