OK, I'm done for now with the suspension and steering mods and now it's time for a Cobb Accessport and then a custom tune. I bought my car very little used (13K) but it did have some upgrades like the MagnaFlow exhaust. On Cobbs website there is a warning about: Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Does the Accessport recognize that another ECU modification has occurred? If there is a previous tune how does one delete it? Sorry I'm an old carburetor guy learning new tricks.
