I have to call BS on tuning and say it is a ploy by after market companies to make money. Adaptive ECU's have been around since the 80's and yet for some reason only domestic and euro cars seem to have the option to use a laptop as a tuner. This is the main reason why I will NEVER buy an Asian import as a performance car. I see no reason why I need to drop a grand on a stand alone ECU when the stock unit is perfectly capable of handling basic tuning. As for power increases, I gained around 9 RWHP on a stock LT1 Z28, add in intake and exhaust that number increased to 27 RWHP. I was also able to adjust my speedo for tires, lower my coolant fan activation temps, and monitor my engine's performance at all times. Since the xD is tuned to 87 octane I have no doubt their would be a power increase if a 93 octane tune was installed.
