I know you don't want to hear it, but remove the MBC.

The best way to get an air/fuel controller is to just remap the ECU (ECUtek or Cobb Accessport) to run more boost. The remapped ECU will run higher boost, and should have the correct A/F ratio at all times. And, if you use the ECU to run more boost, you can get rid of that MBC.

 

i can remap my stock ecu right ? how much does it usually cost ? im just learning about this reflashing thing .......

so the remapped ecu makes the turbo produce more boost? so i dont need the mbc..........!

thanks


by the way i live in hawaii and no one does reflashes down here i have to send it somewhere in cali ...

 

An ECUtek reflash will run ~$650 for 02/03 WRXs and ~$750 for 04+ WRXs and STis. If you don't have a local tuner, I'd look at Cobbs AccessPort software. I think its a little cheaper, and you won't have to ship your ECU to cali.

 

Sounds Good , Thanks For The Help !

 

what about a vishnuperformance.com reflash

 

Vishnu stuff is top of the line (and priced accordingly). Their products are generally excellent. Vishnu's off the shelf remaps may be a little less versatile than Cobb's in terms of what mods can be accomodated, but if you take their advice on how to use their products, you will probably have a fast car.
