COW software
IS it a night and day difference? Can you drive to his shop and have it done while you wait? I have tried to call them but they are out of the country.
You can have it done while you wait, I'd guess. From anecdotal accounts of people having it done, they will drive the car w/ you in the passenger seat holding the laptop that is doing the logging and will periodically stop to adjust and then more logging. Lather, rinse, repeat.
I have read posts from folks who have had it done who were pleased, more so of a difference on A4's though as I guess TQ mgmt plays a larger role there.
I too am pondering this course of action. I have already had a dyno tune done but that's mostly WOT tuning; i'd like to have something logged/adjusted during normal driving conditions though.
