07 wrx sti ap issue
i have an 07 wrx sti. when i flash the stg 1 map onto my ecu, my turbo seems to lag a little bit. when i flash stg 2 map, it seems my turbo lag even more. when I originally have the stock map on my car, my turbo kicks a lot harder and my car pull harder. Can anyone help explain what is going on with my car and what i should do? the ap says my boost is good (17 psi), which is about right, but my turbo seems to lag a lot. And the ap says my 1/4 time is 14.2 and 0-60 is 5.68, which i think is kinda slow for stg 2. Any help would be good.
