My initial reasoning for the GDE specific ECO tuning kit.....
Added performance and improved MPG are two benefits. But the kit also allows you to revert back to the original OEM map at any time down the road. Or if a dealer or independent shop ever restores the ECU coding, I can put the tuned code back on. I don't have to worry about GDE being in business years from now or shipping ECUs back and forth. With their kit I'll have the tools to take care of it myself. Their tool also allows me to read and clear fault codes. I know I could get cheaper tools for that. But it's nice that it's included with their kit. It has everything I wanted, and nothing I didn't. And I know I'm saying all this without receiving or installing anything yet. So time may change my attitude about it. But I've only read positives so far, so I think it'll work out well for me.
