hey guys, im picking up an 05 wrx next week that i checked out and liked a lot. It had catless up and down pipes and a 3 in catback exhaust. and a cold air intake. when i took it on the highway i was getting 10-11psi of boost. I have a tactrix cable and im familiar with mapping from my 02 wrx i had last year. starting out fresh again with my new 05 can some guys here give me tips on what to tune for this? i want a target boost of 14psi. thanks for any help. oh ya and im only able to get 91 oct where i live.
