Hi,Can anyone advise me on the following.I have an option of fitting a boost controller on MY02 STi and I need to know which of the two available is the best. Blitz SBC DC from Japan or MRT TMS 1
from Australia.any info will be appreciated.

 

General consensus will probably be neither ie. let the ECU do the work.

 

Go with Blitz SBC-ID, change the dwonpip too, to get the beast from your TURBO.

 

Thanks for the info guys,vehicle was shipped from Japan with Apexi Performance GT exhaust and Apexi Power intake air filter,do I still need a downpipe ??

 

No idea what the MRT product is like, but I have used other blitz boost controllers, and in my opinion, they are very good.
Apparently with a bit of work the stock ecu can give good boost control, but an electronic boost controller makes it easy for everyone to do it, and accurately too.
