Yeah, headers change things a bit, maybe not much. You'd be best off to wait until the rest of the exhaust system is installed, I think. I bought the tuning kit that had jets, metering rods and springs, and ended up going richer on both rods and jets by 4 numbers each. Not a big change, but it worked OK, and I was getting 18.5 MPG on my commute, the afternoon of which was bumper-to-bumper from LAX up to about Sunset Blvd, on the 405. I'm sure the mileage would have been better if I could have jetted home like I went to work in the morning, which was pretty much 75 mph the whole way.
