SES Code - What to do? Got the code checked out and it said, "Catalytic Efficiency". Does this mean my cat is clogged? The car still feels strong and responsive to me?
I got an appointment with Straight Line Performance on the 28th to get my Nitrous tune and this crap pops up. I don't have enough cash right now to go headers and such but I'm worried about having a clogged cat mess up my numbers.

Catalyst efficiency can mean either a manlfunctioning cat or a bad rear O2 sensor. If it doesn't have any drivability problems I would just have them shut off the rear O2's when you get your tune done. Clogged cats will not necessarily throw a code like that, more likely it will cause misfire due to backpressure.
