I just got the Xfire back tonight. Tested for a faulty IC pump and replaced it immediately. My car still acts the same though, but I think what its doing is normal. Off the line my car is great, accelerates very quickly through all the gears no problem. But say Im going about 40-50 mph and im on a straight road gliding, (with my foot off the throttle) now is it normal for the car to hesitate slightly when I step on it hard? The rpm's will go up and it launches me and it has no problem accelerating 100mph+. I have the Sprintbooster installed and it seems to work great so I figured that has nothing to do with it. I guess this is normal with automatics?

Thanks
