Default MAP rescaling and power loss.

I'm throwing a po106 code and also have a lazy, sporadic o2 in bank 2. With that said, will those cause a noticeable power loss from a dead stop to wot run? I do not personally tune my car, but have a copy of data file and my map at idle is 70's, which according to what I've read, the max is 62kPa at 0%tps and 800rpm. So as soon as I get back with tuner I will have him rescale those. Just wondering why the car felt super sluggish at the track..hoping this might be the Prob??

If your car has a cam, a vacuum leak and/or any number of other issues, your idle can be in the 70's. Just means it's making a little less vacuum. You should never have to rescale a stock map sensor.
