Hi,need some info on this,I have an 05 sti and was wondering how much bhp and torque you can squeeze out of it with its original ecu? I have a 3" milltek system which removes the second cat (the one nearest the tail pipe) a K&N short ram intake and a hks dump valve fitted at the minute.Before i go for the remap i will be upgrading the fuel pump and fitting stainless equal length headers.everything else is pretty much standard.Any info would be great.
cheers,davy.

 

with a remap you should see approx 330bhp
