Do you have a auto or 6speed? I have the Edge EVO 2 with a 6 speed and the tow setting aint much. I run mine in the race mode all the time and watch my EGT's. It is nice for the code reader but apparently it wont read ABS brake codes(my lights on now and it says no codes stored). It takes awhile to change programs on it. Dont know how well it does with the auto trannys. I have never really played with any of the custom settings on it. The way you can set limits on it for EGT, RPM, Boost,Etc. is nice. It will flash red when you hit the limits. If I wouldve found these forums before I bought it I would have gotten a DP tuner. I hear really good things about them. You can get a Economy tune that they say really helps fuel mileage and I hear they have a drivthru tune that quiets the motor down. You can pretty much change them on the fly too, I think. But youll have to buy gauges separate where the Edge has them. When I get the money I will be getting a DP but keeping my Edge for the gauges. With the mods in my sig I get 17 mpg around town with it in the race setting. Not trying to talk you into a DP though. The Edge is a good entry level programmer for the money, I think. Hope this helps.
