Anybody with the NA have the ECM tune with WERKS? I'm thinking about buying the ECM with the +10WHP tune and would like to know how it is and if you can tell a difference.
All I needed to know!! Sounds like a nice tune and the Solstice could use better response.I have had a Werks tuned ECM in my 07 5spd NA for over 3yrs now and have been VERY satisfied from day one. You will feel a difference. It doesn't make it a supercar, but it wakes it up and makes it more responsive across the board. it has never thrown a check engine light and has made no noticable difference in fuel milage.
