Hey Guys,
I am planning a list of mods before I get a full dyno tune done. Currently my 2004 WRX STI has got a full turbo back exhaust (custom made - bought the car with it on), not too happy with the exhaust tone and cabin resonance. Due to the car overboosting heaps, i got the boost pill drilled out slightly, just until i could save enough for a tune. I've also got a lot of wastegate chatter as well that I'm hoping to get rid of with the tune, and/or parts. I am planning to install the following before getting it tuned at Torque Performance:
1. GFB Mach 2 Recirc BOV
2. Grimmspeed 3-port Boost Solenoid
3. AdrenalinR Muffler - Try fix some of the in cabin resonance
3. K&N Typhoon short ram Intake and intake silence delete - Not sure if this is the best intake to get, any ideas?
4. Any aftermarket wastegate actuator to fix the wastegate chatter and provide better response - Not sure which one to get yet.
The plan is to get all of these parts, and install just before getting a tune done. What do you guys rekon?
Cheers.
