once the ecu has been reflashed with the cobb ap, does the si-drive still do anything? if the si-drive is changed post-reflash does it mess anythign up? do you need to re-reflash?

AP does nothing to the SI-Drive.

SI-Drive is used as normal.

Really? When did they change? How much of a difference is COBB # compared to normal #?

Judging from my brother's '07 STi, the power jumped up 30ish horses (ricer math... :)) equal or more in TORQUES, but the real change was the smooth slam into your seat. No stutter, no nothing. Also, max psi went up 2-3 psi, depending on gear and ambient temp.

I've heard the AP for our leggies, especially my '08, is totally useless in terms of power increase. I've heard the contrary. I've heard you get anywhere from 0-40 hp/ TORQUES increase...

Short story: No EFFin idea, mate.

i dont see why it should be much different... its not like they redesigned the powertrain... they did take out the cat in the UP so my ricer math says plus 10 hp over previous years :lol:
