Im 19 and got an 05 STi a couple of months ago. This is my first turbo car. Can anyone give me some info or links to info about the benefits of a boost controller and weather i should go with a manual or electronic one! Thanks

 

A manual boost controller is more accurate. but you will have to tune your car if you get it. i recommend you getting a turbo back exhaust, engine management (accessport, ecutek, or utec), then get a boost controller and tune.

 

i have tbe exhaust, upipe, accessport, cai, lw flywheel/crank pulley. so thats what ill be doing. thanks alot man

 

A boost controller is useless on this car, especially for a stock turbo. The ECU can be programed (tuned) to control the boost in a much smoother and precise way, in essence it is an electric boost controller. I would recommend you talk to a local tuning shop like GST Motorsports or research Open ECU tools.

 

alright thanks
