Post cat o2's and tune

[PC_GUARD]

So for a long time I've had cat inefficiency cel, and I corrected that today. No more cel

As far as I know there should NOT be any difference with the way the engine runs, as far as what the post cat o2's say. My car pulls HARDER now, since clearing the codes.

Any explanations?

I had never heard of this but makes sense. I reloaded a fresh tune let it idle for 10, then proceeded to do an Italian tune up on it lol

Even with iats in the low 100s ish, it pulls like it did with 50 degree air..

Wished I had done this earlier. A gen 3 auto thought he was going to bury me on a run today... ummm nope
