This is my first tuner so I have nothing to compare it to but bone stock and there is little if any difference. Yes my truck is still under warranty. How would a reflash help? This would mean that there has been a problem since the beginning. I have heard of several others from other forums having the same issues. I also heard that ford tuned in a lag on purpose. I also wondered if it may have something to do with the fact that my truck uses a computer driven throttle instead of a cable.
