Thanks for the thread very informative, btw I am an old guy too 42
, helped me a lot on deciding to do a stage 2 on my 13 WRX sedan. I already have the Q-300 installed (love the sound) very quiet, COBB AP, drop in K&N filter. For stage 2 I am going with the Maddad V2 DP, Forge BPV, Bulletproof TMIC kit, and thinking instead of a pro tune just getting a Torqued Performance stage two map for $85. Anything else I should tackle while I am at it? Any opinions appreciated.
