Originally posted by all_bark they were both the first pulls.
so compare those first pulls with the first baseline pull.
I'm thinking that you did not do an ECU reset, so...my guess is that you'll see more power from the cats now that the ECU has had some time to adapt. Yes?

Originally posted by zxsaint jjellyneck, I agree. I've got kinetix hf cats and they came alive in terms of power and sound after 2 days and about 100 miles.
My mpg even adjusted back to normal during this period.
ZXsaint--you're going to do a dyno soon, correct? That will essentially show the difference between cats and no cats on your car, and also importantly.....after the ECU has had some time to adapt. Again, I'm also concerned with the possible lean condition at the low to mid RPM's.
