ss/sc help problem!!!!!!
bingo, car goes from dynamic to maf only at around that rpm on an 05 so if your sputtering right then it's probably your maf.
easiest way to check your maf using hpt v2.22.
go to the editor:
engine>airflow>dynamic airflow lower the setting to 2400/2400 take a drive and if your maf is bad it should start to stutter above 2400 rpms

colder doesnt always mean better. If you have a set of stock plugs try them at idle.
I had a similar issue when i was tuning my car and i hit "smooth" on the timing table and it did the same thing since it advanced timing in other cells. Also KR'd like hell in the upper band under WOT.
just shooting out ideas.
also the startup is fine. Mine will go 1-2k and then hover while it is warming up. pre-warmup setting in hptuners can fix it but it isnt detremental.
