Has anyone one experience sluggish on EC V5 D mode driving around town? It seems the car is unresponsive driving around tow and feel there are bogging when apply throttle. I suspect that the fuel mixture might be rich.
When i switch back to stock file, it certainly feels more peppy.

 

Give EC a call/email. I had a similar bogging issue and they fixed it.

 

get v6 while your talking to them!
