When did you start doing that? I've been having idle issues shortly after having a BBK Full turbo installed @ CBRD. Vacuum is crap at idle, too. My MIL.SPEC TB was purchased about a year ago.

How many miles on the BISS screw do you see that kind of corrosion>?

Also, how do you activate SAS mode in evoscan? just bought it the other day and am a little confused about SAS. I'm looking for the internet how-to right now, just hoping someone could help me with a link or a quick answer. thanks!

i did find this interesting faq on evoscan about a galant owner having issues...i don't have all the equipment to perform the troubleshooting, but it does make me want to reset the ecu with ecuflash to the stock software and adjust the BISS screw from there....

I am having this issue right now but it only started after I replaced my timing belt. Maybe my car was tuned when my timing was a little off. Thinking about adjusting the biss screw. Where can I buy the tactrix cable?

rough idle inquiry

Hey Just curious did you ever get this resolved? I have the same idle issue now as well with the tephra mod.

I took my Evo down to Ivey Tune last February and had the car retuned and did a speed density conversion on it at that time. Much better.
