Ive had my SAFC tuned and in for about 3 weeks but just recently my car seems not as quick as it usually is. When the safc was working good and i was on the highway going around 70, let off and get back on the throttle it wouldnt make the little PUH noise that resembled a backfire. Now the car is doing it again and the car just doesnt feel as fast as it did. This all happened one morning when i was driving to school, the night before that it was fine. I tried resetting the ECU and it is still the same, i also pulled the codes and all im getting is for the bank 2 sensor since i have no cats. BTW i reset the ECU using the fuse method, is it better to do the terminal? Also my throttle settings are 10% low and 50% high, should i change the high throttle and make it say 60 or 70 or even higher? Sensor settings are hotwire 4 in 4 out. I also then tried setting all value to zero and seeing if it runs different and i couldnt tell a difference. Any recommendation? The SAFC still shows that its correcting.
