just curious to know for those who have upgraded their A5 2.0T with the Stasis ECU and exhaust upgrade...
- are you seeing any changes in mpg with the ECU upgrade? stasis told me that with the ECU upgrade, i should see an improvement in mpg.
- stasis told me that the exhause sound between the touring vs challenger is not too much difference. I asked them if they have any recording of both exhaust, which they don't. any comment?

thx
