AP V2 Stage 2 Map Compared to Stock STi Maps

So I have a 07 STi and I just installed my Turbo Back System (COBB 3" Catback and 3" Invidia V2 Catless Downpipe. I went for a small spin with some friends right after installing just my turboback and my friends said it PULLED pretty hard. Then I installed the COBB AP v2 with the stock 91 Octane map and they said it doesn't seem like it pulls as hard. Has anyone ran into this kind of issue? I was thinking if I should go back to my stock map and have my check engine light running untill I decide to get a protune.

Another question is if I decide to go back to my stock map the the AP downloaded from my car, how would I do that? Would I go uninstall the AP or would I have to choose the stock map it downloaded?

Thank You!

Boost creep from no EM probably caused it to pull a lot harder before.

Run the AP stage 2 it's safer...

I'd get a protune if you are planning to upgrade your turbo and other goodies.

If you are just planning to stick with a stage 2 map I'd go with an Opensource stage 2 map. Then sell the Cobb AP.
