I assume you mean stage 1 Cobb map ??
No way a stock wrx makes that much power do the ground. 265 hp do not go down to 251 at the wheels. If so, i'm more than surprised.
if it's a stage 1 mapping, then the AFR has been "ajusted" to make it safe.
That's the main reason why i put a cobb stg 1 on mine...reliability... that and a CBE.
