Hello,
Customer brought in an 08 solstice with some upgrades and wants another tune done. The stock ecu has a trifecta tune on it so no reading/writing going on. Dont have access to a "return to stock file" and emailed them over a week ago with no reply as to such a file.
So if we buy a junkyard ecu and license with HP tuners will dealer still need to program anything(ie key code is bosses' concern)
Searched and searched and nothing definitive and I don't specialize in HP tuners so thanks for your time.
Derek
