So I live in California and I own a 2007 STi. I just got my Invidia Catless Downpipe, 3' Cobb SS Catback Exhaust System and my AccessPort v2. I was looking around Cobb's website and they have 2 different stage 2 maps for 91 octane, so here is my question. One of the maps say

Stage 2 using 91 octane fuel. Requires turboback exhaust. 345HP (+18%)/ 385 lb-ft (+33%)

and the other one says

Stage2 designed specifically for AZ/CA/NV 91 octane. 343HP (+17%)/ 379 lb-ft (+31%)

Which one am I supposed to use? I'm going to assume the second one because its actually geared for the people who live in Arizona, California, and Nevada, or am I wrong? My other question is that I was looking at the requirements for both map settings and they say they both require a HIGH FLOW CATALYTIC CONVERTER, the thing is I am running catless to kill the ozone so my friend can't go snowboarding this winter, is it okay to run the map even though I am running catless?

Thank You!

 

oh ya its fine to run catless. and if you live in cali i would use the second map just because it is designed for the low quality of gas in those states. the second one will work great! i am running catless setup with stage two and it works great!
