I am thinking to modify my 05 WRX in the summer, here are my IDEAL MODS:
I will mod them for sure,however, i was wondering that how much WHP will I gain from these?
Also, what if i dont get a UTEC, is there a BIG difference based on my mods?
since there is none tunning shop specialized in Suby where i am living, i dont know if i would get a UTEC or AP.
I've read a few threads about Ap, they have claimed that detonation and stalling have happened to 04s and 05s, so it's really a hard decision for me...
please give ur advises, i will be really appreciated.
